摘　　要：概述了闪烁体材料研究现状和一些重要性质，阐述了掺杂激活离子Ce^3＋的闪烁体材料的重要参数、性质以及发展状况，重点介绍了几种典型的陶瓷闪烁体及其性能并总结了闪烁体材料的制备方法。展望了稀土多晶陶瓷闪烁体代替单晶闪烁体在医学成像设备探测器领域的巨大推动作用。The current research status and some important Properties of scintillators are summarized in this paper. The important parameters, properties and development of the Ce^3＋ doped scintillators are expounded. Several typical ceramic scintillators and their performances are introduced emphatically. And the preparation methods of scintillator materals are summarized. It is a trend that the ceramic scintillators will replace the scintillation crystals. Ceramic scintillators will play an enormously action in the area of medical imaging equipments.
