摘　　要：铈掺杂钇铝石榴石(YAG∶Ce)黄色荧光粉的形貌和粒度对其发光性能及其应用均非常重要,理想的形貌应是晶粒尺寸可控的球形。本文总结了制备方法、工艺参数及后处理条件在YAG∶Ce荧光粉形貌调控中的研究概况,分析了各种形貌调控手段的优缺点,归纳了粉体形貌与粒度调控的主要特点。Both particle size and morphology of cerium-doped yttrium aluminium garnet （YAG： Ce） yellow phosphors could exert significant influence on their phtoluminescence as well as further applications. It has been demonstrated that the desired morphology is spherical with a controlled size. In this paper, progresses of morphologic and size control of YAG： Ce phosphors by the synthesis methods, technology parameters and post- treatment techniques were summarized, were discussed, and the main features of the advantages and disadvantages of morphologic control measures regulation and control for powder morphology were concluded.
