| 英文摘要 | A red-emitting phosphor, eu3+-doped ca9ligd2/3(po4)(7), was synthesized by the conventional high-temperature solid-state reaction. x-ray powder diffraction (xrd) analyses confirmed the pure crystalline phase of whitlockite-type structure. the excitation spectra of eu3+ doped ca9ligd2/3(po4)(7) were measured in the vuv and uv region indicating an efficient energy transfer process from the host and gd3+ to eu3+ ions. upon excitation with vuv and uv radiation, the phosphor showed strong red emission around 611 nm corresponding to the forced electric dipole d-5(0)-> f-7(2) transition of eu3+ ions. the vuv- and uv-excited luminescence spectra of ca9ligd2/3(po4)(7): eu3+ together with the dependence of the integrated emission intensities on the doping levels were investigated. the eu3+ ions were investigated by a tunable laser as an excitation source. the excitation spectra of f-7(0)-> d-5(0) transitions suggest that there are two families of inequivalent sites for eu3+ in this host. the concentration quenching and crystallographic site-occupancy of eu3+ ions in ca9ligd2/3(po4)(7) host were discussed on the basis of the site selective excitation and emission spectra, the luminescence decay and its crystal structure. |
