| 摘 要： | The barium titano-silicate phosphors doped with Eu3+ were synthesized by high temperature solid state reaction. The structures of as-synthesized samples were characterized by powder XRD. The maximum peaks of emission spectra of Ba2TiSi2O8 and Ba2TiSi2O8∶Eu3+ were respectively located at 450 and 618 nm, coming from the transitions of charge-transfer bands of Ti4+-O2- and forced electric-dipole transition 5D0-7F2 of Eu3+. The luminous mechanisms of Ba2TiSi2O8 and Ba2TiSi2O8∶Eu3+ were suggested. The effects of concentration of Eu3+ on the luminous performance of Ba2TiSi2O8∶Eu3+ were also studied and the results showed that the optimum concentration of Eu3+ was 0.12 mol per mole of matrix.
