Abstract

Dependence of crystal structure and luminescence property of Gd₂Si₂O₇(Ce:GPS) was investigated using poly-crystalline samples synthesized by a solid state reaction method. Three types of crystal structures and different luminescence spectra were observed according to concentration of cerium. The largest luminescence intensity was observed for orthorhombic structure whose cerium concentration was between 0.75 and 2.5 mol%.
