英文摘要	a series of ca2sral2o6:ce3+,li+,mn2+ phosphors have been synthesized by traditional solid state reactions. the structure and photoluminescence properties of the samples together with the energy transfer from ce3+ to mn2+ ions have been investigated in detail. the obtained phosphors can be excited efficiently by uv excitation and exhibit a broad blue-green emission band peaking at 470 nm and an orange-red emission band at 610 nm, which result from the f-d transition of the ce3+ and the t-4(1)-(6)a(1) transition of the mn2+ ions, respectively. by varying the doping concentration of the mn2+ ion, a series of tunable colors including white are obtained at an irradiation of 355 nm. the possible energy transfer mechanism was proposed in terms of the experimental results and analysis of photoluminescence spectra and decay curves of the phosphors. the critical distance between the ce3+ and mn2+ ions has been calculated by both the concentration quenching method and the spectral overlap method. preliminary studies on the properties of the phosphor indicated that our prepared ca2sral2o6:ce3+,li+, mn2+ phosphor might have potential application as a single-phase white-emitting phosphor for wleds.
