SYNTHESIS AND CHARACTERIZATION OF Y2SiO5:Ce3+ PHOSPHOR MATERIALS BY SOL–GEL PROCESS

Y2SiO5:Ce3+ particles was synthesized by sol–gel process. In all samples treated at 1100°C, monoclinic X1 phase for all cerium concentration. Luminescence spectra shows broad Ce3+ luminescence in Y2SiO5 host, which picks around 450 nm. The synthesized and calcined powders were characterized by thermogravimetry-differential scanning calorimeter (TG-DSC), X-ray diffraction analysis (XRD), scanning electron microscopy (SEM) and photoluminescence spectra (PL).
