摘要(Abstract)：

采用高温固相法合成了Y_2WO_6:Nd~(3+)/Yb~(3+)及Y_2WO_6:Nd~(3+)/Yb~(3+),Bi~(3+)系列近红外发光材料,研究了其晶体结构、发光性能、荧光寿命,并讨论了Bi~(3+)的掺入对其近红外发光的敏化作用。Bi~(3+)的掺入不仅显著增强了样品中Nd~(3+)/Yb~(3+)的特征近红外发光强度,还使Y_2WO_6:Nd~(3+)/Yb~(3+)的激发光谱红移。随着Nd~(3+)/Yb~(3+)浓度的升高,Bi~(3+)的荧光寿命逐渐变短,表明样品中存在Bi~(3+)到Nd~(3+)/Yb~(3+)的能量转移。Nd~(3+)和Yb~(3+)的浓度为9%时,能量传递效率分别为85%,88%。根据Inokuti-Hirayama(I-H)理论模型分析表明Bi~(3+)到Nd~(3+)/Yb~(3+)的能量传递为电偶极矩-电偶极矩相互作用。因此,Y_2WO_6:Nd~(3+)/Yb~(3+),Bi~(3+)可作为一种光谱转换材料,有望提高硅太阳能电池的光电转换效率。
