摘　　要：近年来,以雪崩二极管和硅光电倍增管为代表的高探测效率、长波敏感的硅基光探测器件技术得到快速发展,这使得具有红光-近红外发光特性的闪烁晶体材料逐渐受到关注。本文综述了红光-近红外发光金属卤化物闪烁晶体的发展历程,重点介绍了基于Eu^(2+)-Sm^(2+)能量传递的新型红光-近红外发光卤化物晶体的发光机理、闪烁性能和实现高效红光-近红外闪烁发光的材料选择原则,并从材料制备和探测器应用的角度分析了红光-近红外发光闪烁晶体发展所面临的问题。In recent years,the technology of silicon-based photodetectors has developed rapidly,especially in avalanche diode and silicon photomultiplier tube,which present high quantum efficiency and high long-wavelength sensitivity.Therefore,the red and near-infrared luminescent scintillation crystals have been concerned.In this review,firstly,the development history of red and near-infrared emission halide scintillation crystals is summarized.Secondly,the scintillation properties and luminescence mechanism of Eu^(2+)-Sm^(2+)co-doped metal halide scintillation crystals are described in detail,and the selection principle for excellent red and near-infrared luminescence material is also discussed.Finally,from the viewpoint of both material preparation and detector development,the problems for red and near-infrared scintillators are analyzed.
