| 英文摘要 | a new langbeinite-type phosphate ksrsc2(po4)(3) has been synthesized by conventional high temperature solid state reaction. rietveld structure refinement, a field emission scanning electron microscope, photoluminescence spectra, quantum efficiency as well as lifetimes were used to characterize the samples. structure refinement reveals that ksrsc2(po4)(3) has two kinds of sr2+ and sc3+ sites for the doped ions to occupy, forming emission centers. the ksrsc2(po4)(3):ce3+ and ksrsc2(po4)(3): eu2+ phosphors both have broad excitation and emission bands due to spin-and orbit-allowed electron transitions. phosphors with tunable blue to blue-green colors were obtained by codoping the tb3+ ions into the ksrsc2(po4)(3):0.03ce(3+) and ksrsc2(po4)(3):0.03eu(2+) phosphors with varying contents. the mechanism of eu2+ --> tb3+ energy transfer is determined to be a dipole-quadrupole interaction in terms of the experimental results and analysis of photoluminescence spectra and decay curves of the phosphors by using the inokuti-hirayama theoretical model. our prepared ksrsc2(po4)(3):ce3+, tb3+ and ksrsc2(po4)(3):eu2+, tb3+ phosphors are of potential value for uv excited wleds. |
