Phosphorescent pigments have been investigated for many years, being the SrAl2O4:Eu2+, R3+ with a structure of the stuffed trydimite type the one which exhibits better luminescent properties. The ceramic synthesis of this pigment requires, however, high temperatures during the firing process, reason why it is necessary to use mineralizers that give rise to problems not only in the firing process but also from an environmental point of view. Besides, a mixture of N-2-H-2 is needed to reduce the Eu (III) to Eu (II) during the heat treatment. This paper reports the synthesis of the compound by means of an alternative method to the ceramic route. In this case the used method is a variant of the Pechini's one because ethilenglycol is not utilized and a resin, difficult to manipulate, is not formed. 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. Luminescence related to Eu3+ 4f crystal field transitions shows a drastic reduction of trivalent Eu concentration when codoping with Dy or Nd. The characteristic broad phosphorescence band centered at 520 nm is observed under ultraviolet illumination and is enhanced in Dy codoped pigments.
