摘要

X射线探测广泛应用于医疗诊断，工业探伤、安防安检等各个领域，其中X射线面阵探测器是影像设备中的关键部件。利用半导体材料一步将X射线转换为电信号，可以实现高空间分辨率。钙钛矿材料由于X射线衰减序数高、载流子扩散距离长、辐照稳定等优势近年来已成为直接型X射线探测器的明星材料。本文简要介绍了直接型X射线探测原理、关键性质及核心材料，阐述了卤化物钙钛矿在直接型X射线探测器中的应用优势，综述了钙钛矿单像素探测器和与TFT集成的面阵探测器的特点及最新研究进展，最后，提出了目前面对的技术挑战和潜在解决方案，对基于卤化物钙钛矿的X射线面阵探测器的未来发展趋势进行了展望。

Abstract

X-ray detection is widely used in medical diagnosis， industrial flaw detection， security and other fields， and X-ray array detector is the key part of imaging equipment. High spatial resolution can be achieved by converting X-ray into electrical signals in one step using semiconductor materials. Perovskite material has become the star material of direct X-ray detector in recent years due to its advantages of high X-ray decay ordinal number， long carrier diffusion distance and irradiation stability. This paper briefly introduces the principle， critical nature and core materials of the direct type of X-ray detection， indicates the advantages of halide perovskite in applying in direct X-ray detector and expounds the characteristics and the latest research progress of both perovskite single pixel detector and TFT integrated array detector. Finally， the current technical challenges and potential solutions are put forward， and the future development trend of X-ray detector based on halide perovskite is prospected.
