英文摘要	a series of novel kbasc2(po4)(3):ce3+/eu2+/tb(3+)phosphors are prepared using a solid-state reaction. x-ray diffraction analysis and rietveld structure refinement are used to check the phase purity and crystal structure of the prepared samples. ce3+- and eu2+-doped phosphors both have broad excitation and emission bands, owing to the spin- and orbital-allowed electron transition between the 4f and 5d energy levels. by co-doping the kbasc2(po4)(3):eu2+ and kbasc2(po4)(3):ce3+ phosphors with tb3+ ions, tunable colors from blue to green can be obtained. the critical distance between the eu2+ and tb3+ ions is calculated by a concentration quenching method and the energy-transfer mechanism for eu2+tb3+ is studied by utilizing the inokuti-hirayama model. in addition, the quantum efficiencies of the prepared samples are measured. the results indicate that kbasc2(po4)(3):eu2+,tb3+ and kbasc2(po4)(3):ce3+,tb3+ phosphors might have potential applications in uv-excited white-light-emitting diodes.
