摘要(Abstract):
合成了系列铕铽双核稀土有机稀土配合物Tb1-xEux(TTA)3Phen,通过差热-热重分析、XRD、红外光谱、紫外光谱和荧光光谱等测试手段研究了配合物的组成、结构和发光性质。由紫外可见光谱可以看出,稀土有机配合物的吸收峰主要来自有机配体HTTA和1,10-Phen;差热-热重分析证明,稀土有机配合物热稳定性较好。荧光光谱和电致发光表明,铽对铕配合物的发光有协同作用。在该系列配合物中,不仅有机配体可以将吸收的能量传递给发光的铕离子使其发光,而且铽离子也可将其吸收的能量通过分子内能量传递给铕离子,增强铕的发光强度。同时就双核稀土有机配合物光致发光和电致发光的特性及掺杂体系的能量传递过程进行了讨论。
