中文摘要：

采用一种基于微流体快速均匀混合的沉淀方法，以碳酸氢铵（NH4HCO3）为沉淀剂制备前驱体。红外光谱（FT-IR）、X射线衍射（XRD）、透射电镜（TEM）和热分析（TG-DTA）等测试结果显示，该方法获得的前驱体经煅烧后可得到分散性好、形状规则、平均粒径为50nm的纯相Nd：YAG纳米粉体。

英文摘要：

Nd ： YAG powders were synthesized by co-precipitation technique which based on microfluid uni- formly mixing at high speed. The properties of Nd ：YAG powders were investigated by FT-IR, XRD, TEM and TG- DTA. The results show that the precursor synthesized by this method are directly turned into pure Nd ： YAG phase without intermediate phases after being calcined. Nd ： YAG nanopowders are obtained with an average particle size of about 50nm, sphere-shaped and good dispersity.
