采用高纯微米级商业原料（≥99.99％）α-Al2O3、 Y2O3和CeO2, 用固相反应法制备了0.3at % Ce3+∶YAG透明陶瓷. 粉体经行星式球磨, 陶瓷素坯在1750℃真空烧结10h, 真空度10-3Pa, 双面抛光后, 厚度为1.2mm的透明陶瓷试样在可见光区500～900nm的直线透过率可达80％左右, 光学均匀性良好. 荧光光谱分析表明, 发射峰位于500～700nm之间, 这是Ce3+的特征发射. 结果表明, Ce∶YAG透明陶瓷的发光性能与相应的单晶相当, 有望作为闪烁材料应用于中低能量射线（α、β粒子等）的探测.
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.
