Paper Title:
Fabrication and Sinter-Ability of Ce3+-Doped YAG Ceramics by Low-Temperature Combustion Method
  Abstract

The phosphors YAG doped with Ce3+ was prepared by low-temperature combustion method. Utilizing the prepared YAG powders as raw material and Li2O-CaO-ZnO-Y2O3-Al2O3-SiO2 glass powder as sintering additive, YAG:Ce3+ ceramics were sintered at 1400-1550°C for 10h in vacuum. The sinter-ability of the YAG ceramics was studied by measuring the linear shrinkage rate. The phase, microstructure and photoluminescence properties of the YAG: Ce3+ powders and ceramics were investigated by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence (PL) analysis. The results show that the sinter-ability properties of YAG:Ce3+ ceramics was mainly associated with sintering temperature and contents of glass sintering additive; the best result was achieved when the sample was sintered at 1500°C and doped sintering additive of 1%.
