Preparation and Coating Process of Nano-scale Y_2O_3:Eu~(3+) Powders

LI Qiajn

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.
