摘要
合成了4种稀土(Ce(Ⅲ)、Nd(Ⅲ)、Dy(Ⅲ)、Er(Ⅲ)1,2-双(2-苯并咪唑基)-1,2-乙二醇配合物,采用元素分析、IR、UV光谱和摩尔电导率等方法对配合物的结构进行表征,测定了固体荧光光谱和荧光衰减曲线.研究结果表明,配合物都是1:3型电解质,它们发射很强的蓝色荧光,荧光寿命为1.95—2.34ns.
Four complexes of 1,2-bis(2-benzimidazolyl) -1,2-ethanediol with rare earth(Ce(Ⅲ), Nd(Ⅲ), Dy(Ⅲ) and Er(Ⅲ) were synthesized and characterized by elemental analysis, IR, UV spectra and molar conductivity. Their fluorescence spectra and decay curves were measured in solid state. It was found that all complexes were 1:3 typed electrolytes, and they transmitted strong blue fluorescence with life-times in range of 1.95 - 2.34 ns.
