摘要

闪烁体广泛用于医疗诊断、工业检测和国土安全等各个领域的x射线检测。金属卤化物钙钛矿（MHP）及其类似物的纳米晶体（NCs）由于其制造成本低、衰变时间快以及量子限制效应产生的室温闪烁而显示出作为x射线闪烁体的巨大优势。然而，进一步工业化仍有许多挑战尚未解决。在此，有必要总结基于MHP及其类似物的NCs的闪烁体的研究进展。在第一节中，概述了闪烁机制和关键参数。然后，对MHP的各种NCs及其类似物用作闪烁体进行了综述。最后，讨论了挑战和展望。人们认为MHP及其类似物的NCs有利于大面积和柔性的x射线探测器。

Nanocrystals of metal halide perovskites and their analogues as scintillators for x-ray detection

Scintillators are widely used for x-ray detection in various fields, such as medical diagnostics, industrial inspection and homeland security. Nanocrystals (NCs) of metal halide perovskites (MHPs) and their analogues showed great advantages as x-ray scintillators due to their cheap manufacturing, fast decay time, and room temperature scintillation from quantum confinement effect. However, there are still many challenges unsolved for further industrialization. Herein, it is necessary to summarize the progress of scintillators based on NCs of MHPs and their analogues. In the first section, the scintillation mechanism and key parameters are outlined. Then, various NCs of MHPs and their analogues used as scintillators are reviewed. Finally, the challenges and outlook are discussed. It is believed that NCs of MHPs and their analogues are favorable for large-area and flexible x-ray detectors.
