CdZnTe是一种高效、高分辨率的室温核辐射探测器，广泛应用于环境监测、医学、工业无损检测、安全检查和空间科学等领域。简要介绍了CZT探测器的工作原理和性能评价。然后讨论了CZT晶体物理性质与CZT探测器性能之间的关系。介绍了CZT探测器的仿真与设计方法。为促进CZT探测器的应用和发展，应加强高质量、低成本的CZT晶体生长技术、CZT探测器的设计与制造以及辐射探测系统的研究。
CdZnTe is an excellent candidate for high efficiency,high-resolution room-tem- perature nuclear radiation detectors,which are being widely used in environmental monitoring,medi- cine,industrial non-destructive testing,security inspection and space science.The working principle and performance evaluation of CZT detector were first described briefly.And then the relationship be- tween the CZT crystal physical properties and the CZT detector performance was discussed.The CZT detector simulation and design methods were presented.For promotion of the application and develop- ment of the CZT detector,the studies on high-quality,low-cost CZT crystal growth technology,CZT detector design and fabrication and the radiation detection system should be enhanced.
