Abstract: 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.

Key words: solid state reaction method, Ce∶YAG, scintillator transparent ceramics
