Rare-earth-activated BaY(2)Si(3)O(10) (BYSO) phosphors were synthesized via a solid-state reaction. BaY(2)Si(3)O(10):Ce(3+) yields an indigo-blue emission peak at 404 nm according to excitation at 334 nm attributed to the Ce(3+) 4f-->5d transition. BaY(2)Si(3)O(10):Tb(3+) typically generates green emission peaks resulting from the 5D4-->7FJ transition. BaY(2)Si(3)O(10):Eu(3+) exhibits red emission peaks upon excitation at 393 nm. The quantum efficiency of these phosphors was found to be 53%, 55%, and 63% of commodity. The results in this work demonstrate that these phosphors with new compositions are good candidate luminescent materials for use in plasma display panels and light-emitting diodes, excited from VUV to UV.
通过固态反应合成了稀土激活的BaY₂Si₃O₁₀（BYSO）荧光粉。BaY₂Si₃O₁₀:Ce³⁺在334nm激发下，由于Ce³⁺的4f→5d跃迁，在404nm处产生一个靛蓝色发射峰。BaY₂Si₃O₁₀:Tb³⁺通常由于5D4→7FJ跃迁产生绿色发射峰。BaY₂Si₃O₁₀:Eu³⁺在393nm激发下呈现红色发射峰。发现这些荧光粉的量子效率分别为商用产品的53%、55%和63%。这项工作的结果表明，这些具有新组成的荧光粉是用于等离子体显示面板和发光二极管的良好候选发光材料，可由真空紫外光激发至紫外光。
