Solution-combustion synthesized highly luminescent CaTiO3:Gd2O3:Eu3+ perovskite nanophosphors for WLED applications

The thermal activation energy of 0.31 eV obtained for Ca0.88Gd0.05TiO3:0.07Eu3+ suggested an appreciable stability against thermal quenching due to the cross-over process. The color parameters, luminescence lifetime, JuddeOfelt parameters and radiative properties have been fairly discussed.
