Fabrication and Luminescence Study of Ce~(3+)-doped YAG Transparent Ceramics

0.3at% Ce∶YAG(Y3Al5O12) transparent ceramics was fabricated by a solid state reaction method,with the high pure(≥99.99%) commercial powders α-Al2O3,Y2O3,CeO2 using as raw materials.The ceramic green bodies were sintered in 1750℃ for 10h in vacuum.The linear transmission of the prepared Ce∶YAG ceramics in visible range 500-900nm reaches about 80% homogeneously(1.2mm thick,double polished).Photoluminescence properties show that the emitting band of the Ce∶YAG ceramics lies in 500-700nm,which is the characteristic emitting of Ce3+.It is concluded that the Ce∶YAG transparent ceramics is a promising scintillator materials especially for middle-low energy ray detecting.
