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Y_2O_3:Eu^(3+)粉体,并采用KAl(SO_4)_2及Na_2SiO_3溶液进行表面包膜处理,在纳米Y_2O_3:Eu^(3+)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Y_2O_3:Eu^(3+)粉体分散性能及表面结构有明显的影响.
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.
