摘　　要：闪烁晶体用于X射线和γ射线等高能粒子探测,在分子医学成像、高能物理、核物理、安全检查、材料无损探伤和地质探矿等领域有着广泛的应用。随着人们对闪烁晶体的更加深入的认识以及晶体生长技术的发展,许多已开发的闪烁晶体的性能得到优化和提高,应用范围也随之扩大,随着应用的更高要求,对闪烁晶体的综合性能要求越来越高,进一步设计、发现、开发和生长具有高密度、优良光学均匀性、高能束粒子阻止本领、高光产额、快衰减、高稳定性、低成本等综合优良性能的闪烁晶体仍然是闪烁材料研究的重点。简要综述了近年来卤化物、钨酸盐、锗(硅)酸盐、铝酸盐和硼(磷)酸盐等重要闪烁晶体材料的研究进展及其闪烁性能和应用前景。Inorganic scintillators as ideal candidates for detection of X-ray, γ-ray, neutron and high energy particles have been widely applied in molecular medical imaging, high energy physics, nuclear physics, security inspection, non-destructive materials flaw detection and geological survey. With the development of crystal growth techniques and the deeper understanding of the scintillation materials, many known scintillators have been optimized with respect to their properties and the application were greatly broaden. New and sophisticated applications have higher demands for scintillation properties of the crystals. Design, discover, develop and produce scintillation materials with better properties such as high density with high stopping powder of energetic particles, good optical homogeneity, high light yield, fast decay, high stability and low cost are still the main tasks. This micro-review introduced the recent research development of inorganic scintillation crystals in the halide, tungstate, germinate, silicate, aluminate, borate, phosphate systems.
