摘要Bi3+ doped YBO3 phosphors are prepared by solid state reaction and their luminescent properties are investigated by using synchrotron radiation instrument. Concentration and temperature dependences of YBO3:Bi3+ luminescence under VUV/UV excitation is observed. The emission and excitation spectra are assigned, and the mechanism for these phenomena is explored, which result from the energy transfer between Bi3+ ions occupying different sites in YBO3 crystal lattice.
