摘要
X射线探测在诸如医学成像、特定晶体结构测定、射电天文学等领域有着非常重要的作用。而传统的用于X射线探测领域的材料如硅、锑化镉等存在制备工艺复杂、成本高、X射线探测灵敏度低等缺点,严重制约了X射线探测领域的发展。近年来,铅卤钙钛矿材料作为备受关注的热点材料,因其具备较大的原子序数、高吸收系数等优点,在X射线探测领域表现出非常优异的性能。而钙钛矿材料体系是一个大家族,不同组分的钙钛矿材料各有其优缺点,即使是同一组分的钙钛矿,根据其结晶性等参数的不同,性能表现也各不相同。本文从钙钛矿材料调控的角度出发,综述了近些年来直接转换型钙钛矿X射线探测器取得的成就,并对未来钙钛矿X射线探测领域的发展趋势做出了展望。
X-ray detection plays an essential role in areas such as medical imaging,determination of specific crys-tal structures,and radio astronomy.However,traditional materials used in the field of X-ray detection,such as sili-con and cadmium antimonide,suffer from complex fabrication processes,excessive cost and low sensitivity to X-rays,which severely limit the development of the field.As a hot topic in recent years,lead halide perovskites have shown excellent performance in the field of X-ray detection due to their large atomic numbers and elevated absorption coefficients.While the perovskite material system is a huge family,different components of perovskite materials have their advantages and disadvantages,and even the same component of perovskite material can have different proper-ties depending on different parameters such as crystallization.In this paper,we review recent achievements in direct-conversion perovskite X-ray detectors from the perspective of perovskite material regulation and provide an outlook on future developments in perovskite X-ray detection.
