摘要 合成一系列关于Eu(III)/Gd(III)与2-噻酚甲酰三氟丙酮(HTTA)、苯甲酸(BA)和邻菲罗啉(Phen)的配合物,并对这配合物进行元素、红外与荧光光谱分析.结果表明:这些配合物的组成为Eu1-x,Gdx(BA)-(TTA)2Phen(x=0~1),配合物Eu(BA)(TTA)2Phen比配合物Eu(TTA)3Phen具有更宽的激发带,且激发带发生明显的蓝移.说明新的配合物已经生成.共发光Gd^3+离子对配合物Eu1-xGdx(BA)(TTA)2Phen的荧光增强非常明显,最佳Gd^3+离子浓度为0.4(摩尔分数).配合物Eu1-xGdx(BA)(TTA)2Phen荧光增强的主要机理是Eu(BA)(TTA)2Phen与Gd(BA)(TTA)2Phen配合物分子间的能量传递. A series of Eu (III)/Gd (III) complexes of benzoic acid (BA), 2-thienyltrifluoroacetonate (HTTA) and Phenanthroline (Phen) are synthesized. Compositions of these complexes are revealed to be Eu1-xGdx(BA)(TTA)2Phen (x=0-l). Their IR spectra and fluorescent spectra are studied. The fluorescent excitation spectra of these complexs show broader excitation hand and a peak position blue shift than that of Eu(TTA)3Phen corresponding to their formation. The fluorescence enhancement of cofluorescence Gd^3+ ions to the Eu(III) complexes is clear. The optimum concentration of Gd^3+ is 0. 4 (molar fraction). The intermolecular transfer between Gd(BA)(TTA)2Phen and Eu(BA)(TTA)2 Phen appears to be responsible for the fluorescence enhancement of Eu1-xGdx (BA)(TTA)2Phen.
