Enhancement of the Luminescent Intensity of Nano-Scale Y_2O_3:Eu~(3+) Powders

Qiang Li

Abstract

Nano-scale Y2O3:Eu3+ powders with different grain sizes and Eu3+ concentrations were prepared by chemical process, and dealed with coating. It was found that the Eu3+ critical concentration of nano-scale Y2O3:Eu3+ powders was increased obviously, and it caused the luminescentintensity improved. In addition, because the hanging bonds on the surface of coating nano-scaleY2O3:Eu3+ powders were mostly vanished, the luminescent intensity was further enhanced.
