Scintillators which could convert high-energy photon such as X- and gamma-ray or charged particles such as electrons and alphaparticles into a bunch of UV-Vis light,have been extensively studied over the past decades and been applied to the medical imaging and dosimetry,security inspection,industrial detection and high-energy physics.In general,the rare earth ions such as Ce3+,Pr3+ or Eu2+ are doped in host crystals due to the fast decay time (typically tens to hundreds ns)and high quantum efficiency of the 5d-4f radiative transitions of these centers.In this review,the maj or achievements from the last decades in the field of inorganic scintilla-tor are described,mainly including the halide,aluminate and silicate compounds.%闪烁体能够快速地将光子如X射线、γ射线或高能粒子如α粒子、β粒子转换成紫外-可见脉冲荧光,因此在过去的几十年中备受学术界和产业界关注,目前已经在核医学成像、安全检查、工业探测、高能物理等领域广泛应用.由于稀土离子如Ce3+、Pr3+和Eu2+等具有5d-4f快偶极允许跃迁,所形成激子衰减时间一般在几十至几百纳秒之间,具有快闪烁响应特性,通常作为发光中心掺杂入不发光的基质中形成闪烁晶体.主要介绍了近几十年来无机闪烁晶体主要包括卤化物、铝酸盐和硅酸盐三类在学术界和产业界中的研究进展.
