超快闪烁晶体Cs2ZnCl4研究进展
Research Progress of Cs2ZnCl4 Ultrafast Scintillation Crystals
摘要
Abstract
The next generation of high energy physics experiments and time-of-flight positron emission tomography imaging require scintillators with ultrafast decay ranging from nanoseconds(ns)to picoseconds(ps)to fulfill the need for higher precision of radiation detection.The Cs2ZnCl4 crystal stands out due to its remarkable advantages of an ultra-fast decay without slow component,a low melting point,non-hygroscopic,as well as the proper emission band match-ing well with commercial photomultiplier tube.In recent years,Cs2ZnCl4 crystal has attracted worldwide research inter-ests as a kind of ultrafast scintillator with core-valence luminescence(CVL).This review emphasis on the research his-tory and progress of Cs2ZnCl4 crystals,including luminescence mechanism,physicochemical properties,crystal growth techniques and the scintillation properties.Particularly,emphasis is placed on the optical and scintillation properties of Cs2ZnCl4 crystal.The application potential of Cs2ZnCl4 crystals as a unique ultrafast scintillator is then concluded.关键词
