摘要： 本文采用高分子网络凝胶法制备了粒径约为20nm的纳米Y2O3：Eu3+粉体，并采用KAl（SO4）2及Na2SiO3溶液进行表面包膜处理，在纳米Y2O3：Eu3+粉体表面获得了约2nm厚的复合氧化物膜，发现包膜处理对纳米Y2O3：Eu3+粉体分散性能及表面结构有明显的影响．

Abstract: Nano-scale Y2O3:Eu3+ powders(the grain size about 20nm) were prepared by the polyacrylamide gel method. After being dealed with coating by dipping in the solutions of KAl(SO4)2 andNaZSiO3, nano-scale Y2O3:Eu3+ powders were covered by an composit oxide layer about 2nm.The obvious effects of coating process on the dispersity and appearance structure of nano-scaleY2O3:Eu3+ powders were found.

Key words: nano-scale Y2O3:Eu3+, coating, Auger electron spectroscopy
