Development of high-performance direct X-ray detector materials: from hybrid halide perovskites to all-inorganic lead-free perovskites

Abstract

X-ray detection plays a vital role in medical imaging, industrial defect detection, security screening and scientific research. Direct X-ray detectors are of greater interest to researchers because they offer the advantages of faster imaging, higher resolution and simpler construction than indirect detectors. Due to their intrinsic properties, traditional materials have inherent problems that limit their performance in detector applications. Perovskite is a new material with excellent properties that has great potential in the field of X-ray detectors. This paper summaries the research progress of perovskite materials in the field of X-ray detectors. First, the problems of traditional materials are listed according to the principle and material requirements of X-ray detectors. Then, the problems and challenges of different types of perovskite materials are divided from the classification of perovskite materials, from organic to inorganic materials, and from halide perovskites to lead-free perovskites. The intention is to provide ideas for the development of more environmentally friendly and higher-performance X-ray detectors.
