英文摘要	A series of Mn2+ doped Ba2MgSi2O7 phosphors with a nominal formula Ba2Mg1-xMnxSi2O7 (x = 0.01-0.13) were prepared by a high-temperature solid-state reaction technique. Their VUV vis photoluminescence spectra, fluorescence decay curves, and low-voltage cathodoluminescence spectra were measured and discussed in detail. The results confirm that the Mn2+ ions enter into the four-coordinated Mg2+ site in Ba2MgSi2O7 host lattice. The main electron-vibrational interaction (EVI) parameters (such as Huang Rhys factor, effective phonon energy and position of the zero-phonon line) were evaluated from the experimental spectra. Furthermore, the concentration and the temperature dependence of the emission intensity and the luminescence decays of Ba2MgSi2O7:Mn2+ were investigated, accordingly the schematic energy levels for Mn2+ in Ba2MgSi2O7 were proposed. Due to the high emission intensity under low-voltage electron beam excitation, a further optimized sample Ba2Mg0.95Mn0.05Si2O7 can be considered as a promising green phosphor for field emission displays (FEDs).
