Sr2CeO4 is not only a novel blue-emitting phosphor holding important application potential, but also a good host lattice for trivalent rare-earth activators. In recent years, more attentions were paid to the photoluminescence performance of the Sr2CeO4 doped with rare-earth. The crystal structure and spectral properties are analyzed for these phosphors. The luminescent performance of Sr2CeO4 phosphors doped with Eu3+, Sm3+, Dy3+ with tunable emission colors is reviewed. Some suggestions are proposed for the further research.
