The Brillouin scattering effect was predicted first by Brillouin [1] and Mandelshtam [2] and for the first time experimentally verified by Gross [3].

Within the scattering process phonons of energy h&Omega; are either created (&Omega;<sub>S </sub>= &Omega;<sup>-</sup>, Stokes scattering) or annihilated (&Omega;<sub>AS </sub>= &Omega;<sup>+</sup>, Anti-Stokes scattering). Generally, in solids three orthogonal polarized acoustic modes of different frequencies &Omega; (p, <strong>q</strong>) are related to each wave vector <strong>q</strong> (p = l, 2, 3) A typical BS spectrum of a solid is shown in fig. 1.</p>\r\n<p>&nbsp;</p>\r\n<table style="margin-left: auto; margin-right: auto; height: 354px;" width="539">\r\n<tbody>\r\n<tr>\r\n<td>\r\n<p style="text-align: center;"><img style="display: block; margin-left: auto; margin-right: auto;" src="upload/images/spectrum.JPG" alt="" width="238" height="324" /></p>\r\n</td>\r\n<td style="text-align: justify;"><em>Fig. 1 Brillouin spectrum (of Hexatriacontane at room temperature).

We have synthesized graphene oxide (GO) following a modified Hummers method, which has been subsequently reduced by electrochemical procedures. This reduction strategy precludes the employment of toxic solvents, leading to a product, electrochemically reduced graphene (ERG), free of contaminants. The characterization of the synthesized nanomaterials has been performed by different techniques such as X-ray diffraction spectroscopy (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The information gathered by this combination of techniques confirms that i) the synthesis methodology affords the production of GO nanosheets, which present a typical lateral dimension of several hundreds of nanometers and a thickness value of 1.3 +/- 0.1 nm, ii) the reduction step has been successfully achieved leading to graphene nanosheets free of oxygen functionalities with an average lateral dimension of at least 1 micrometer and a thickness value of 2.8 +/- 0.2 nm. Once we have confirmed that both materials have been successfully synthesized, we have studied the effect of the effect of their inclusion in biosensing platforms on the analytical response, selecting a lactate oxidase based biosensor as a model system.

Electronic transport (magnetoresistance and electroresistance) and magnetic properties showed important anomalies in the temperature interval between 60 and 150 K, below the metal-insulator transition. Scanning probe microscopy revealed changes in BaTiO3 surface morphology at those temperatures. La0.7Ca0.3MnO3 thickness is a critical factor: 120-angstrom -thick films showed large anomalies sensitive to electric poling of the BaTiO3, whereas the behavior of 150-angstrom -thick films is closer to that of the reference La0.7Ca0.3MnO3 samples grown on SrTiO3. We propose that, through inhomogenous strain and electric polarization effects, the ferroelectric substrate induces an inhomogenous spin distribution in the magnetic layer. This would imply the coexistence of in-plane and out-of-plane ferromagnetic patches in La0.7Ca0.3MnO3, possibly interspersed with antiferromagnetic regions, as it has recently been theoretically predicted.

The deep blue emission is unchanged by donor peripheral substituents while an increasing acceptor character produces a reduction of the optical gap, an increased Stokes shift and eventually leads to the appearance of a new electronic level and to the simultaneous deep blue (413 nm) and green (552 nm) emission in solution. Quenching by concentration increases with the acceptor character but is lower as the tendency of these compounds to aggregate is stronger. Solution processed thin films present optical and morphological qualities adequate for device fabrication and similar electronic structure compared to solutions with an emission range from 423 nm up to 657 nm (red), demonstrating the possibility of tuning the energy levels by chemical functionalization. We have fabricated and characterized single-layer solution processed organic light emitting diodes (OLED) to investigate the influence on transport and emission properties of the substituting species. We analyzed the I-V response using a single-carrier numerical model that includes injection barriers and non-uniform electric-field across the layer. As a result, we obtained the electric field dependence of the mobility for each device. Best results are obtained on the most electron rich derivative functionalized with six donor methoxy groups. This material shows the highest emission efficiency in solid state, due to aggregation-induced enhancement, and better transport properties with the highest mobility and a very low turn-on voltage of 2.8 V.

A net magnetic moment is measured in the nanocrystals and films at 5 K, as well as large coercive fields, contrary to bulk MnP. X-ray absorption spectroscopy and diffraction show that epilayers and films contain MnP grains in the nanometric range with average Mn-P bond lengths very close to those of bulk MnP. The MnP film lattice parameters are almost identical to bulk values (within 0.5%) and the main crystallographic preferential orientations are those also present in the epilayers but with different relative populations. Overall the local structures of all MnP forms are very similar, except for indications of more disorder in the nanocrystals. Such combined changes of T(N) and T(C) are in apparent contradiction with the known response of bulk MnP to strains induced by hydrostatic, uniaxial or chemical pressure. We conclude that the differences in the low temperature magnetic behavior are most probably originated by local structural disorder at the surface of the nanostructures and by finite size effects.

An essential ingredient is supplied by the internal pressure of the R3+ cations upon a decrease in size along the rare-earth series, from La to Lu: the concomitant compression of the MnO6 octahedral units for the small rare earths provides progressively shorter Mn-O distances and improves the overlapping between Mn and O orbitals, thereby promoting superexchange and enhancing T-C by 50 K along the series.

The study demonstrates that the detected ferromagnetism is related to regions of high density of defects in SnO2 induced by doping under particular conditions. The observed room-temperature ferromagnetic (RTFM) signal does not scale to Mn content but increases with the number of interfaces and their roughness. The presence of Mn in 3+ oxidation state in the SnO2 lattice is a necessary condition but is not enough to promote ferromagnetism which also requires the presence of Sn2+. The high oxygen deficiency induced by Mn doping in the tin-oxide layers is mostly compensated by the formation of the stable SnO phase. Moreover, the RTFM signal decreases upon annealing either in O-2 rich or in vacuum atmospheres. The combination of Mn with SiO2, Si, or Al produces paramagnetic signals but no ferromagnetism; consequently SnO2 is a crucial ingredient of this RTFM. The observed ferromagnetism may be explained by short-range ferromagnetic correlations between Mn probably mediated by induced holes at oxygen sites of SnO2 in the vicinity of trivalent Mn3+ doping ions. The inhomogeneous Mn distribution inside tin oxide at the multilayer interfaces may produce large enough regions with high defect concentration to allow long-range ferromagnetic order. All undoped SnO2 films, grown in a wide set of different conditions, show paramagnetic signals with high-J values but no ferromagnetism is detected probably because of the high density of defects required to establish a ferromagnetic order based in a short-range mechanism.', '[Espinosa, A.; Garcia-Hernandez, M.; Prieto, C.; de Andres, A.] CSIC, Inst Ciencia Mat Madrid, E-28049 Madrid, Spain; [Menendez, N.] Univ Autonoma Mad', 'Espinosa, A (reprint author), CSIC, Inst Ciencia Mat Madrid, Plaza Murillo 2, E-28049 Madrid, Spain.', '', 'CSIC; Spanish "Ministerio de Educacion y Ciencia" [MAT2009-08786]', 'This work has been supported by CSIC and by the Spanish "Ministerio de Educacion y Ciencia" under the Contract No. MAT2009-08786.

In order to find the most suitable conditions to stabilize the ferromagnetic ordering in this system, the evolution of the magnetic properties has been studied for films in which the Si3N4 layer thickness was maintained constant while that of the Mn layer was varied, [Mn(t(m))/Si3N4(3.4 nm)](n), and conversely, in [Mn(0.7 nm)/Si3N4(t(sn))](43) samples, in which the Mn layer thickness was kept constant while varying the Si3N4 layer thickness. Structural, compositional, electronic and magnetic characterizations have been performed by means of x-ray reflectometry, Rutherford backscattering spectrometry, x-ray photoemission spectroscopy, x-ray absorption, and superconducting quantum interference device for further knowledge of the magnetic-structural relationship in this system. Our results show that the peculiar magnetic behavior of these films is mainly related to the stabilization of a slightly distorted Mn3N2 phase that is induced by the Si3N4 at the interfaces. For samples with larger Mn layer thickness, metallic Mn and Mn3N2 phases coexist, which leads to a reduction of the total magnetization per Mn atom due to the presence of metallic Mn. For small Mn layer thickness (t(m) <0.86 nm), where noncontinuous Mn3N2 layers are formed, the magnetization decreases noticeably due to the superparamagnetic size limit. It has been found that the best conditions for the stabilization of the ferromagnetism in this system occur when both, the manganese-rich and the silicon nitride layers, are continuous and with similar thickness, close to 3.5 nm.

This molecule crystallizes forming a highly ordered columnar structure in which stacked molecules are situated at two alternating distances (3.53 angstrom and 3.68 angstrom) along the column as determined by single crystal X-ray diffraction analysis. These short intermolecular distances between adjacent units, make this system an ideal candidate for charge-transport processes along the stacks. Relevant parameters for transport (i.e. internal reorganization energies, transfer integral) have been estimated by DFT calculations at a 6-311 G(d,p)/B3LYP level of theory. As a double check for the transfer integral, the electronic band structure of a one-dimensional stack of molecules has been computed. The electronic properties of this material have been studied both theoretically and experimentally. Its HOMO value is found to coincide with Au work function (Phi(Au) = 5.1 eV), thus low barriers are expected for hole injection from gold electrodes. The hole mobility of this material has been predicted theoretically considering a hopping-type mechanism for the charge-transport and determined experimentally at the space charge limited current (SCLC) regime of the current-voltage measurements. Both theoretical and experimental values are in good agreement. The high hole mobility (mu(min) = 0.4 cm(2) V(-1) s(-1)) of this material points towards its useful application in the organic electronics arena.

The phases distinctive of both phase diagram sides are consecutively detected. All magnetic, transport, and electroresistance properties are found to be anisotropic. Below the ferromagnetic ordering, T-C1=143 K, we have detected a second magnetic transition (T-C2=125 K) with an easy ferromagnetic direction along the c axis and antiferromagnetic order (AF) along the a and/or b axes. The glassylike behavior of the ferromagnetic phase disappears when the AF correlations become long ranged. The magnetocrystalline anisotropy remains below the orbital ordering transition (T-C3=73 K) with a strong anomaly in the coercive field at 30 K. The system is insulating at any temperature with different activation energies depending on the direction of the current below T-C1. The observed magnetic anisotropy below T-C2 is consistent with a homogeneous picture of the system as the ordered orbital polaron lattice proposed for the x=0.125 compound. Typical negative magnetoresistance (MR) for single crystals is detected, except at temperatures between both magnetic transitions, T-C3 < T < T-C2, where the positive MR is due to the promotion of the orbital order. Applied magnetic fields up to 14 T could not remove the orbital order while low-current densities (j=10(-8) A/cm(2) at T=20 K), when applied along the AF axes, are able to destroy the orbital order and delocalize the carriers inducing a metalliclike conductivity and reducing the resistivity by a factor of up to 10(7).

At low temperatures the magnetic field-induced ferromagnetism (FIFM) persists even at B=0 and is quenched to a fractional value of the total number of spins. This incomplete ferromagnetism decreases with increasing temperature and disappears at T-m=10-20 K. T-m depends on the hole concentration "x" and increases as x-->0.3. We interpret this as the incomplete relaxation from FM toward AF spin orientation, resulting in the canted antiferromagnetism (CAF). This is in contrast to the "virgin" (zero-field cooled) magnetic ground state where no ferromagnetic component could be detected. Due to the strong competition between FM and AF orders, three successive AF transitions are detected. The low-temperature transition at T-3= 27 K has a strong influence on FIFM, resulting in the minimum magnetic field required to trigger the FIFM state. Furthermore, the T-3=27 K transition results in a pronounced anomaly in the temperature variation in magnetization.

Cross-sectional transmission electron microscopy (TEM) analyses revealed the presence of a homogeneous distribution of 15-30 nm wide nanoclusters in a dislocation-free GaP matrix that is fully coherent with the substrate. The nanocluster facets are predominantly aligned along the (220) planes of the GaP matrix and selected-area electron diffraction patterns in TEM indicate that the nanoclusters are coherent (or semicoherent) with the single-crystal GaP matrix. The Mn: P composition ratio in the nanoclusters was determined to be 1.00 +/- 0.05 from parallel electron energy loss spectroscopy analyses. Increasing the MCTMn flow rate during film growth resulted in an increased concentration of MnP nanoclusters in the epilayer while their dimensions remained virtually unchanged.

The presence of oxygen during deposition is responsible for these structural changes, as well as for an oxygen enrichment in the NiO films, which leads to changes in their electrical properties. The electrical resistivity of the films decreases with the oxygen content of the plasma, which suggests p-type conductivity due to oxygen enrichment in the NiO lattice. Indeed, an analysis of the EXAFS oscillations at the Ni-K edge confirms the lattice expansion and a decrease of the Ni-Ni coordination number when the oxygen content of the plasma increases, which points towards an increasing presence of Ni vacancies for larger values of the O-2/Ar ratio.

Measurements have been performed on four polycrystalline samples and four single crystals, allowing us to compare and extract the essence of dielectric response in the material. High-frequency dielectric function is found to be epsilon(HF)=30, as expected for the perovskite material. Dielectric relaxation is found in the frequency window of 20 Hz to 1 MHz at temperatures of 50-200 K that yields to colossal low-frequency dielectric function, i.e., the static dielectric constant. The static dielectric constant is always colossal, but varies considerably in different samples from epsilon(0)=10(3) to 10(5). The measured data can be simulated very well by blocking (surface barrier) capacitance in series with sample resistance. This indicates that the large dielectric constant in PCMO arises from the Schottky barriers at electrical contacts. Measurements in magnetic field and with dc bias support this interpretation.

LCMO thin films in a thickness range between 2.4 and 27 run were grown by DC-sputtering on SrTiO3(001). We distinguish two different crystallographic structures associated to the 2.4 and 27 nm thin films, respectively. The 27 nm film structure corresponds to a tetragonal perovskite (space group Pbnm), as has been reported for bulk LCMO. For the 2.4 nm film the La/Ca ions are located at the regular position of an ideal perovskite and the MnO6 octahedrons are aligned along the c-axis. The MnO2 stacking layer (basal plane) is distorted and coplanar to the a-b crystallographic axis with an anti-correlation between octahedron layers. This observed distortion is not compatible with the Pbnm space group. The new phase, which cannot be excluded to coexist at the interface of thicker films, can be described, as an example, through an 14/mcm or Pbcn space group. Based on the observed structure, plausible models to explain their transport and magnetic behaviour are proposed. For the 2.4 nm film, an octahedron in-plane (basal plane) distortion induced by the substrate is observed. Thicker films behave structurally and magnetically as bulk-like materials.

The use of gaseous currents is not required, since the organic matter of the gel itself generates the reducing atmosphere. Once mixed the different solutions, the gel formation takes place by the addition of citric acid and further elimination of the solvent. The gel is dried, fired and analyzed by X-ray diffraction.

In particular, we study RMnO(3) (R=La, Pr, Nd, Tb, Ho, Er, Y, and Ca) and the different phases of Ca- or Sr-doped RMnO(3) compounds as well as cation deficient RMnO(3). The spectra of manganites can be understood as combinations of two kinds of spectra corresponding to two structural configurations of MnO(6) octahedra and independently of the average structure obtained by diffraction techniques. One type of spectra corresponds to the orthorhombic Pbnm space group for octahedra with cooperative or dynamic Jahn-Teller distortions, with stretching modes as the main features and whose frequencies correlate to Mn-O distances. The other spectrum is associated to regular but tilted octahedra whose modes can be described in the rhombohedral R (3) over barc structure, where only bending and tilt modes are observed. The main peaks of compounds with regular MnO(6) octahedra, such as CaMnO(3), highly Ca-doped LaMnO(3), or the metallic phases of Ca- or Sr-doped LaMnO(3), are bending and tilt MnO(6) octahedra modes which correlate to R-O(1) bonds and Mn-O-Mn angles, respectively. In low and optimally doped manganites, the intensity and width of the broad bands are related to the amplitude of the dynamic fluctuations produced by polaron hopping in the paramagnetic insulating regime. The activation energy, which is proportional to the polaron binding energy, is the measure of this amplitude. This study permits to detect and confirm the coexistence, in several compounds, of a paramagnetic matrix with lattice polaron together with regions without dynamic or static octahedron distortions, identical to the ferromagnetic metallic phase.

This process is strongly favored by the presence of chemical defects that also promote weak localization of the carriers into polaron clusters that can be overcome by relatively low magnetic fields. This behavior is characteristic of temperatures near T-c where the bandwidth is reduced and localization, due to intrinsic disorder and chemical defects, is more probable.

Thermal expansion effects on the phonon frequencies are not relevant above 300 K in La and Pr samples. The intensity of the spectrum decreases drastically as the temperature increases but is still observable in the pseudo-cubic phase. The remaining spectral weight, above the Jahn-Teller transition, can be explained by the presence of dynamic Jahn-Teller distortions that lower the symmetry of the cubic perovskite. The Raman spectra of LaMnO3 and PrMnO3, which presents a similar structural transition temperature, shows the same behavior while that of YMnO3 is clearly different. This is explained by the fact that this compound presents a stronger cooperative Jahn-Teller distortion.

The phonon frequencies of the main peaks of Pbnm structure have been correlated to structural characteristics, such as bond-lengths or bond angles, obtained from the analysis of neutron diffraction data. According to the structural and Raman behavior, these compounds can be classified into two groups: one includes La, Pr, and Nd, and the other includes the rest. This classification also correlates to the different behavior of their magneto transport properties when doped. A structural transition to a cubic or quasi-cubic perovskite, above 800 K, can be deduced from the phonon spectra for YMnO3 orthorhombic compound. (C) 2001 Elsevier Science B.V.

A large increase of resistance is observed at temperatures below the ferromagnetic order temperature where a metallic regime is expected. The behavior with temperature and frequency of the resistance of low temperature annealed pellets can be explained taking into account that two kinds of conduction paths are present in the sample: low resistive metallic ones, where the carriers percolate through well connected grains and highly resistive channels for high intergrain boundaries that behave as capacitors. In order to obtain the conduction mechanisms for non-doped RMnO3 samples, we have measured the resistance in a large temperature range up to 1400 K.

Eu3+ luminescence has been investigated in the off-resonance condition for several excitation energies as a function of temperature. Raman phonons and several Raman crystal field transitions are obtained. From reflectance experiments (between 1.25 and 3.7 eV), D-5 multiplet levels are determined. The schemes of the lowest electronic levels of both Eu3+ sites have been established combining data from these three spectroscopies which show a good agreement with the calculated values. Crystal field parameters are obtained in an approximation to a C-2v local symmetry. The high value of fourth-rank parameters indicates a partial covalent character of Eu-O bonds. The obtained spin-orbit coupling value, zeta = 1280(70) cm(-1), is similar to those in other europium oxides. The variation of the Raman crystal field transition intensity with temperature presents an unexpected deviation with respect to the ground state population, specially pronounced in the low temperature range. The peaks corresponding to the three highest levels of the F-7(2) multiplet are anomalous probably due to some hybridization with the nearest oxygen levels. The relative intensity of luminescence peaks associated with transitions from D-5(0) and D-5(1) levels vary versus temperature as a function of the probability of the non-radiative decay.

Consequently, the elastic constants have been determined by Brillouin scattering as a function of the stoichiometry. The C-44 elastic constant presents, as a function of the stoichiometry, a clear minimum for the [Li]/[Nb]=1 in the melt sample. This behavior must be related to the existence and competition of two kind of defects, i.e., extended defects induced when growing samples not at the congruent composition, and point defects present in nonstoichiometric samples. The optic phonons seem to be dominated by the point defects. The linear increase of the phonon lifetimes, with respect to an ideal stoichiometric sample, can be due to the scattering by the static imperfections and to an increase of the anharmonic scattering. Several Raman peaks, which appear when the [Li]/[Nb] ratio decreases, are related to the presence of Nb in antisites. The width of some particular phonons can be used to estimate the [Li]/[Nb] ratio whenever a line shape study and a good correction, taking into account the instrumental broadening, is carried out.
