中文摘要	a series of single-composition phosphors ca-5(po4)(2)sio4:ce3+, tb3+, mn2+ have been prepared via a high-temperature solid-state reaction process. the ce3+ emission at different lattice sites has been identified and discussed. the energy transfer from ce3+ to tb3+ and mn2+ ions has been validated. the emissive colors of ca-5(po4)(2)sio4:ce3+, tb3+/mn2+ samples can be adjusted from blue to green and from blue to red-orange by the energy transfer of ce3+ -> tb3+ and ce3+ -> mn2+, respectively. more importantly, white emission has been obtained through adjusting the relative concentrations of ce3+, tb3+ and mn2+ ions in the ca-5(po4)(2)sio4 host under uv and low-voltage electron beam excitation, respectively. additionally, the temperature-dependent photoluminescence and the degradation behaviors of cathodoluminescence under continuous electron bombardment for as-prepared phosphors have been investigated in detail. the results reveal that the ca-5(po4)(2)sio4 host is stable enough to protect the photoluminescence and cathodoluminescence properties of ce3+, tb3+ and mn2+ ions from being affected. tunable luminescence and the stable structure suggest that ca-5(po4)(2)sio4:ce3+/tb3+/mn2+ phosphors have great potential in the application in wleds and feds.
