The phosphors Sr2CeO4: 1.5 mol% Eu3+ was synthesized by solid state reaction method in air at 1200 ?C. These samples were characterized by X-ray diffraction (XRD), Fourier Transform infrared (FTIR), and Photoluminescence (PL) techniques. The photoluminescence (PL) spectra of pure and Eu3+ doped Sr2CeO4 were recorded at room temperature. Sr2CeO4 phosphor was effectively excited around 254 nm and observed a broad emission band peak around 468 nm. XRD data revealed that the structure of Sr2CeO4 is orthorhombic and the mean crystallite size of Sr2CeO4 and Sr2CeO4:1.5 mol. % Eu3+ were 22nm and 90 nm respectively. The color coordinates of Sr2CeO4:1.5 mol. % Eu3+ were x = 0.3434 and y = 0.3351 and CIE coordinates reveale
