Most common thermometric luminescent nanoprobres contain alkaline and/or halogen ions which poisson currently used catalysts, for instance the well known NaYF4 host based compounds. Our IMPETUSS project (PID2021-128090OB-C21) aims the development of eficient luminescence nanoprobes compatible with standardly catalyzed reactions. In this direction we develloped alkaline and halogen-free β´Gd2(MoO4)2 nanoprobes doped with Yb3+, Er3+ and Tm3+. We defined three different ratiometric channels to determine temperature from 20 to 600ºC with optimised sensitivity.
