Co-doped lutetium aluminum garnet scintillation ceramic and preparation method thereof
The invention discloses a co-doped lutetium aluminum garnet scintillation ceramic and a preparation method thereof, the scintillation ceramic is prepared from Lu2O3, Al2O3, CeO2 and CaF2 powder as raw material powder through a solid phase reaction method, the scintillation ceramic is of a garnet structure, the general formula of the scintillation ceramic is (Lu0.997-xCaxCe0.003) 3Al5O12, x is greater than 0 and less than or equal to 0.005, and after Ca < 2 + > is co-doped, the scintillation performance of Ce: LuAG ceramic is greatly improved. The scintillation ceramic has higher light yield, faster scintillation decay time and better thermal stability, solves the problems of low light yield value, large slow components in scintillation response, poor thermal stability and the like of the scintillation ceramic prepared in the prior art, and is simple in preparation method, short in time consumption, low in cost, suitable for industrial production and suitable for industrial production. The method can be applied to medical imaging and high-energy physics (HEP) experiments.
本发明公开了一种共掺杂镥铝石榴石闪烁陶瓷及其制备方法，所述闪烁陶瓷以Lu2O3、Al2O3、CeO2和CaF2粉体作为原料粉体，由固相反应法制备得到，闪烁陶瓷为石榴石结构，其通式为(Lu0.997‑xCaxCe0.003)3Al5O12，其中0＜x≤0.005，Ca2+共掺杂后，Ce:LuAG陶瓷的闪烁性能得到了很大的改善。该闪烁陶瓷具有更高的光产额、更快的闪烁衰减时间及更好的热稳定性，解决了现有技术制备的闪烁陶瓷低光产额值、闪烁响应中较大的慢速组分及热稳定性差等问题，且该闪烁陶瓷制备方法简单、用时短、成本低适合工业化成产，可应用于医学成像和高能物理(HEP)实验。
