Lu_2O_3:Eu与(Lu,Gd)_2O_3:Eu透明闪烁陶瓷的性能对比研究

Comparative Study on Properties of Lu_2O_3:Eu Transparent Scintillation Ceramics and (Lu,Gd)_2O_3: Eu Transparent Scintillation Ceramics

高密度的Lu_2O_3:Eu陶瓷在X射线激发下可以观察出极强的红光发射,显示了该陶瓷在X射线探测成像领域有着巨大的应用前景;通过Gd共掺得到(Lu,Gd)_2O_3:Eu透明陶瓷可以改善Lu_2O_3:Eu透明闪烁陶瓷光谱性能,该文对两种陶瓷的多种性能进行对比,同时介绍了已经商用的(Y,Gd)_2O_3:Eu,Pr、GOS、GGG陶瓷的闪烁性能;阐述了单一组分的闪烁陶瓷性能单一,不能满足应用条件,多组分的闪烁陶瓷将会成为研究的热点。

A strong red emission peak was observed in Lu2O3： Eu transparent scintillation ceramic with high density under X-ray excitation.It was verified that Lu2O3： Eu transparent scintillation ceramic was a promising candidate material in X-ray detection imaging application.（ Lu,Gd）2O3： Eu transparent scintillation ceramic was obtained via Gd2O3 doped Lu2O3.The result showed that the doped ceramics showed a ameliorative spectral property compared with Lu2O3： Eu transparent scintillation ceramics.The properties of Lu2O3： Eu and（ Lu,Gd）2O3： Eu ceramics were investigated.The ceramics were commercialized applied,such as（ Y,Gd）2O3： Eu,Pr,GOS,GGG scintillation ceramics,the scintillation properties of Lu2O3： Eu and（ Lu,Gd）2O3： Eu ceramics were discussed.It was illuminated that the one-component scintillation ceramics with sole property may be not satisfied with requirement of current applications.Fabrication of multi-component scintillation ceramics with diversified properties will become a research focus.
