摘　　要：辐照损伤是医疗影像、大科学装置、航天工业等各领域面临的共性核心问题,材料的高能辐照稳定性和损伤机理研究是其走向实际应用必不可少的环节。新型钙钛矿半导体材料在高能辐射探测领域极具应用前景,但其高能辐照稳定性仍然存在争议,辐照损伤机理尚不清晰。本文探讨了高能辐射环境中钙钛矿的损伤机制及影响辐照稳定性的主要因素,并提出了增强钙钛矿材料抗辐射能力的潜在策略,旨在获得钙钛矿结构与辐照稳定性的构效关系,为钙钛矿辐射探测器件的开发提供有效的参考依据。Radiation damage is a common core problem in various fields,such as medical imaging,large-scale scientific facilities,aerospace industry,etc.The study of high-energy radiation stability and damage mechanism of materials is an essential step for their practical application.As new semiconductor materials,perovskites have shown great application prospects in high-energy radiation detection.However,the high-energy radiation stability of perovskite materials is still controversial and the radiation damage mechanism is not clear yet.This paper discusses the damage mechanism of perovskites in high-energy radiation environments and identifies the primary factors affecting their radiation stability.Additionally,potential strategies to enhance the radiation resistance of perovskites are proposed.The study aims to elucidate the structure-activity relationship between structure and radiation stability of perovskite,providing valuable insights for the development of perovskite-based radiation detectors.
