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%.
