摘要
YAG不仅是最重要的固体激光材料,也是有希望的闪烁材料,自YAG晶体问世以来,晶体缺陷研究对YAG晶体的性能改进和发展起到了十分关键的作用.反位缺陷是YAG和LuAG晶体中一种特殊类型的缺陷,它对晶体中载流子的输运过程和其它性质有重要影响,本文介绍YAG和LuAG晶体中反位缺陷的类型、产生原因及其对性能的影响和作用机制.最后,还对如何测定反位缺陷和抑制反位缺陷的方法进行了简略讨论.
YAG is not only one of the most important solid laser crystals,but also a promising scintillation material. Since it comes out,the studies of defects in YAG crystal have played key roles on the improvement and development of crystal properties.As a special kind of defect in the YAG and LuAG crystals,anti-site defects exert crucial influence on the carrier transportation and other properties.In this paper,the type and the origin of the anti-site defects in the YAG and LuAG crystals,as well as the mechanism of their effects on the crystal properties are described. Also,how to detect and inhibit the anti-site defects in the YAG and LuAG crystals are discussed.
