Preparation and Luminescence Property of Monodisperse GdxY2-xO3:Eu3+ Nanospheres

doi:10.7517/j.issn.1674-0475.2006.03.180

Abstract

Abstract: Monodisperse Gd_xY_2-xO₃:Eu³⁺ nanoparticles are successfully synthesized by homogeneous precipitation method.SEM,TEM, XRD and photoluminescence(PL) spectra have been used to characterized the morphology,crystalline structure,and PL property of samples.By PL spectra, it is found that proper Gd³⁺ doping of Y₂O₃:Eu³⁺ can obviously enhance the PL intensity.When compared with combustion method,the max PL intensity is enhanced to some extent.But at the same time,the contents of costly Gd³⁺ decrease from 80% to 20%.In addition,the effect of Eu³⁺ concentration on PL enhancement has also been studied.

Key words: nano, Gd_xY_2-xO₃:Eu³⁺, rare earth, luminescence
