英文摘要	ca8mglu(po4)(7):ce3+,tb3+,mn2+ (abbreviated as cmlp:ce3+,tb3+,mn2+) phosphors were synthesized by a high-temperature solid-state method. x-ray diffraction (xrd), photoluminescence (pl) spectra, gsas structural refinement, and absolute quantum yield and lifetimes were used to characterize the samples. increasing the ce3+ doping concentration in the cmlp host shifts the emission peak from 360 to 374 nm. under uv excitation, the energy transfers (ets) from ce3+ to tb3+ and from ce3+ to mn2+ in the cmlp host occurred mainly via a dipole-quadrupole mechanism, and the critical distances of the ion pairs (r-c) were calculated by the quenching concentration method and spectral overlap method, respectively. the emission colors of the cmlp:ce3+,tb3+,mn2+ samples could be adjusted from blue to green, and eventually to orange-red by the et between ce3+ and tb3+/mn2+. moreover, a white light emission tunable over a wide range was obtained by precisely controlling the contents of ce3+, tb3+ and mn2+. temperature dependent luminescence spectra proved the good thermal stability of the as-prepared phosphor. based on the good pl properties and varied hues of the cmlp host achieved by adjusting the doping concentration of the activators (ce3+, tb3+, mn2+), cmlp might be promising as a host material for solid-state lighting and display fields.
