英文摘要	a novel single-composition ca-4(po4)(2)o:ce3+,eu2+ phosphor emitting white light was synthesized by conventional solid-state reaction for light-emitting diode applications. x-ray diffraction, photoluminescence spectra, and luminescence decay spectra were used to characterize the samples. energy transfer from ce3+ to eu2+ ions was observed in the co-doped samples, and the transfer mechanism in the ca-4(po4)(2)o:ce3+,eu2+ phosphors was dipole-dipole interaction. the emission hue of ca-4(po4)(2)o:ce3+,eu2+ was found to vary from blue (0.165, 0.188) to white (0.332, 0.300) and eventually to orange (0.519, 0.366) by precisely controlling the ratio of ce3+ to eu2+. the combination of a 380 nm near-ultraviolet chip with a ca-4(po4)(2)o:0.02ce(3+),0.012eu(2+) phosphor produced a diode emitting white light with ultra-wideband emission and a correlated color temperature of 4124 k. overall, results indicated that the prepared samples may be potentially applied in white-light-emitting diodes.
