近几年,由于在惯性约束聚变诊断,核反应机理和时间飞行正电子发射断层扫描(TOF-PET)等多个重要领域具有潜在的应用,ZnO 基超快(衰减时间小于1ns)闪烁体受到广泛关注。文章综述了 ZnO基单晶闪烁体的发展。有文献报道,Ga3+、In3+、Sc3+和 Fe3+等几种不同的 n 型掺杂 ZnO 单晶体已经被广泛用作极紫外、X-射线、α粒子等重离子的检测和成像。随着晶体生长技术的发展,提高了 ZnO 基闪烁体的性能,进而拓宽了其应用范围。上述 ZnO 材料促进了新一类超快半导体闪烁体的兴起。因此, ZnO 基闪烁体的下一步的工作,主要是通过优化浓度和掺杂剂的种类,以提高光输出。

In recent years,ZnO ultrafast scintillation monocrystal (decay time <1 ns)has received extensive attention as it has been adopted in various fields such as inertial con-finement fusion diagnosis,nuclear reaction mechanism and time of fly positron emission tomography(TOF-PET),etc.In this article,the development of ZnO ultrafast scintil-lation monocrystal has been summarized.It is reported that several type of n-type ZnO monocrystal of Ga3+,In3+,Sc3+and Fe3 +have been widely adopted in extreme ultra-violet,X-Ray and the detection and imaging of heavy ion such asαparticle.With the de-velopment of the crystal growth technique,the performance of the ZnO scintillant has been improved,hense the application field of it has been broadened.The above mentioned ZnO materials promotes the rise of new type of ultrafast scintillation semiconductor. Therefore,the further research work on ZnO scintillant is to increase the light output of it through the optimization of the concentration and the type of dopant.
