| 英文摘要 | in this paper, eu2+-doped and eu2+/mn2+-codoped ba1.3ca0.7sio4 phosphors were synthesized by means of a conventional solid-state reaction process. the single-phase purity was checked by means of x-ray diffraction and the rietveld method. under excitation at 390 nm, the emission spectra of the eu2+-doped phosphors exhibit a broad-band emission centered at 500 nm caused by the electric dipole allowed transition of the eu2+ ions. the emission spectra of codoped phosphors show one more broad emission centered at 600 nm attributable to the transitions from the t-4(1)((4)g) -> (6)a(1)(s-6) of mn2+ ions. the luminescent color of the codoped phosphors can be easily adjusted from blue to red with variation of the mn2+ content. the energy transfer mechanism from the eu2+ to mn2+ ions in ba1.3ca0.7sio4 phosphors has been confirmed to be the resonant type via dipole-quadrupole interaction, and the critical distance has been calculated quantitatively. all these results demonstrate that the eu2+/mn2+-codoped ba1.3ca0.7sio4 phosphors can be a promising single-phase, color-tunable phosphor for near-uv white-light-emitting diodes after a further optimization process. additionally, a great red shift from 593 to 620 nm has been observed following the increase of mn2+ content, and the phenomenon has been discussed in relation to the changes in the crystal field surrounding the mn2+ ions and the exchange interactions caused by the formation of mn2+ pairs. |
