Enhancement of the Luminescent Intensity of Nano-Scale Y2O3:Eu3+ Powders

Abstract

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.

Key words: nano--scale Y₂O₃:Eu³⁺, luminescent intensity, critical concentration, coating
