Abstract: Monodisperse GdxY2-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, GdxY2-xO3:Eu3+, rare earth, luminescence
