| 英文摘要 | in this paper, ce3+ doped and ce3+, mn2+ co-doped na2ba6(si2o7)(sio4)(2) phosphors were synthesized via a high temperature solid-state reaction. the rietveld refinement analysis of the x-ray diffraction patterns confirmed the formation of the single phase of na2ba6(si2o7)(sio4)(2). the pl spectrum of the ce3+ single-doped phosphor shows a broad asymmetric band extending from 350 to 600 nm peaking at 420 nm under the excitation of uv light. also, the low temperature (5 k) pl spectrum shows clearly three peaks at 375, 420, and 451 nm, which is in accordance with the ce3+ ion site in the host. the ce3+, mn2+ co-doped phosphors show a blue emission band and an orange emission band, and the corresponding cie coordinates intuitively indicate the tunable colors from the blue to green area. and the energy transfer mechanism from ce3+ to mn2+ in the host has been verified to be a dipole-quadrupole interaction. in addition, the emission intensity of na2ba6(si2o7)(sio4)(2):0.01ce(3+) phosphor slightly changed with the temperature increase from 300 to 450 k, revealing that the obtained phosphor possesses an excellent thermal stability, which makes it an attractive candidate phosphor for white lighting emitting diodes. |
