摘要
用氯化稀土与邻氨基苯甲酸铵和 2 ,2′ 联吡啶在水溶液中反应 ,合成了邻氨基苯甲酸 2 ,2′ 联吡啶 Eu La固体稀土配合物。经元素分析 ,其化学组成式为 (Eu0 .5La0 .5)L3L′(其中L =邻氨基苯甲酸 ,L′ =2 ,2′ 联吡啶 ) ,测定了配合物的红外光谱和荧光光谱。实验结果表明 ,两配体与稀土离子形成了配位键 ;用不发光的La3
Complex of europium and lanthanum with o aminobenzoate 2,2′ dipyridyl was synthesized in solution. Elemental analysis showed that the composition of the compound is (Eu 0.5 La 0.5 )L 3L′,where L is o aminobenzoate and L′ is 2,2′ dipyridyl. Its infrared and fluorescence spectra were investigated. The spectral data showed that the chemical bonds were formed between both ligands and the rare earth ions. The fluorescence spectra indicated that the emission intensity of europium could be enhanced if a part of europium ion in europium complex was substituted by La ion.
