Scintillator is a unique class of luminescent materials, which is extensively used in many fields such as nondestructive testing, medical imaging, space probes, etc. Compared with the disadvantages of traditional scintillator materials which have high cost, are fragile, have long response time and low spatial resolution disadvantages, metal halide perovskites are considered to be the most potential scintillator materials in X‐ray detection and medical imaging due to their preeminent performance of radiative absorption, carrier transportation, high photoluminescence, high atomic number (Z), high‐quality elements, and low‐temperature solution process. However, this material has blemishes such as poor stability and low luminous efficiency in the application of X‐ray detection. In recent years, many start‐of‐art and momentous works have been carried out to solve these problems. Herein, it is intended to summarize the progress of perovskite scintillators to date and propose a scheme for the development of their bottlenecks. First, the physical phenomena and main parameters of scintillators are summarized. Second, the classification of scintillator materials and their application of perovskite scintillators are outlined. Finally, the issues that remain in the application of perovskite scintillators and provide a simple outlook for possible directions in future applications are discussed.

Halide Perovskite，X射线检测的潜在闪烁体
闪烁体是一类独特的发光材料，广泛用于无损检测，医学成像，空间探针等许多领域。与传统闪烁体材料相比，缺点是成本高，易碎，响应时间长，低空间分辨率的缺点，金属卤化物钙钛矿被认为是X射线检测和医学成像中最有潜力的闪烁体材料，因为它们具有出色的辐射吸收，载流子传输，高光致发光，高原子序数（Z），高质量元素和低温溶解过程。但是，这种材料在X射线检测应用中存在诸如稳定性差和发光效率低下的瑕疵。近年来，为解决这些问题已经进行了许多先进的重大工作。本文旨在概述钙钛矿闪烁体的最新进展，并提出解决其瓶颈的方案。首先，概述了闪烁体的物理现象和主要参数。其次，概述了闪烁体材料的分类及其在钙钛矿闪烁体中的应用。最后，讨论了钙钛矿闪烁体的应用中仍然存在的问题，并为将来的应用提供了可能的方向的简单观点。
