Gd2O3 is a useful host material because its crystallographic structure is similar to that of Y2O3, a well- known host lattice for efficient phosphors. Detailed study on Gd2-x-yO3EuxMy (x=1m%, y=0, 0.1, 0.5, 1 m% and M=Li+, Zn2+) have been carried out, preparing it by urea combustion method and precipitation method at 8000C. Photoluminescence properties, SEM, XRD, FTIR measurement have been carried out to characterize their structural, morphological and luminescent properties. Result shows that by incorporation of Li+ and Zn2+ in Gd2-xO3Eux (x=1 m%) would lead to remarkable increase of photoluminescence, by both methods and it is found that precipitation method is good method among both, for preparing in term of efficiency, morphology and quantity of final out put product. The enhance photoluminescence intensity assigned to the local distortion of crystal field surrounding the Eu3+ activator by Li+ and Zn2+ ions co-doping having less ionic radii. Thus the prepared phosphor can be used as a good candidate in the field of light emitting phosphors, advance flat panel displays or color screen.
