Progress in Halide Perovskites and Their Derivatives for X-Ray Scintillators
Abstract
Halide perovskites (HPs) and their derivatives are considered as promising candidates for next-generation scintillator materials due to their strong x-ray absorption capability, favorable optoelectronic properties, and relatively low manufacturing costs. This review offers a systematic overview of recent advancements and potential applications of HP scintillators. First, the working mechanism of x-ray detection is explained based on the fundamental physical processes involved in the interaction between x-rays and materials. Second, optimization strategies for key performance parameters such as light yield and response-decay time are summarized, with particular emphasis on techniques for modulating the light transmission. Finally, the major challenges impeding the practical implementation of perovskite scintillators are discussed, and an outlook on potential future developments is provided.
