A blue emitting Sr2CeO4 phosphor doped with the rare earth erbium and co-doped Terbium were synthesized by Solid state reaction method. The powders were fired at 12000 C for four hour. The photoluminescence study of these materials reveals the emission in the bluish green region. The X-Ray diffraction pattern reveals that the size of particles. The materials were conforming from EDAX and the morphological study of material gives from SEM. In present paper we reported the excitation and emission of pure Sr2CeO4 phosphor and SrCeO4: Er, Tb which gives emissions with good intensity at 474, 527, 536, 550 and 568 nm.
