稀土卤化物钙钛矿X射线闪烁体研究进展
X-ray Detectors Based on Rare-Earth Halide Perovskites
摘要
Abstract
X-ray scintillators are core functional components in fields such as medical diagnosis,industrial inspection,and security screening,where they play an irreplaceable role.In recent years,metal halide perovskites have drawn extensive attention as X-ray scintillator materials,attributable to their structural flexibility,high atomic numbers of constituent ele-ments,tunable emission spectra,and high photoluminescence quantum yield.The combination of rare earth elements with excellent luminescent properties and metal halide perovskites not only inherits the merits of each material but also enables precise regulation and performance optimization of the luminescent behavior.This is achieved through the coupling of the unique energy level structure of rare earth ions and the outstanding semiconductor characteristics of perovskites.Consequently,rare earth halide perovskites have emerged as a focus of research in the field of X-ray scintillators in recent years.Based on the remarkable progress achieved by rare earth halide perovskites in the field of X-ray scintillators in recent years,this paper presents a systematic review of the physical properties,structures,and scintillation performance of sev-eral typical rare earth halide perovskite systems.Additionally,the current research challenges are summarized,and some improvement suggestions are put forward.关键词
