摘要: 0.5% Ce3+ doped BaCa2MgSi2O8 phosphor was prepared by a conventional solid state reaction method. Luminescence spectra as well fluorescence decay were monitored in the VUV-UV range. emissions are assigned to cerium ions on Ba2+ site, and five 4f-5d excitation bands of determined at low temperature. The light yield is estimated be around 10 600 ph MeV-1 under X-ray excitation. absorption near-edge structure (XANES) explored study energy transfer efficiency optical centers from each element phosphor; results show that contributions luminescence not identical for element.
