Synthesis Photoluminescence Studies of Y2O3 Phosphor Doped with TB,EU AND GD

Present paper reports the synthesis and characterization of Tb, Eu and Gd activated Y2O3 phosphor. This phosphor was prepared by solid state reaction method and characterized by Photoluminescence, XRD and SEM techniques. PL excitation peaks for Y2O3 Phosphor doped with Eu, Gd & Tb were observed at 252,268 and 304 nm, whereas the emission spectra of Y2O3 Phosphor doped with Eu, Gd & Tbshows peaks around 485,544,552,595,613 and 632nm. The phase formation is determined by X-Ray Diffraction(XRD) and it is around 20nm.The morphology is also observed
