| Abstract: | Sr2CeO4/Ln3 (Ln=Er,Ho,Tm) phosphors are synthesized by microwave radiation method for the first time.The luminescent properties of the samples are investigated and up-conversion luminescence of Er3 ,Ho3 and Tm3 doped Sr2CeO4 phosphors are observed.The spectra indicates that the energy transfer takes place from the triplet excited state of MLCT(metal-to-ligand charge transfer) state for Sr2CeO4(sensitizer) to the rare earth ions (activator). |

| Keywords: | Sr2CeO4 Er3 Ho3 Tm3 luminescence up-conversion luminescence microwave radiation |
