摘要
以丁二酸(H2L)为第一配体,1,10-邻菲罗啉为第二配合物,合成系列(Eu_(1-x)Y_x)_2L_3 phen固体粉末配合物。利用红外光谱、荧光光谱、DSC等对该系列配合物结构及发光特性进行了研究。结果表明,钇离子的掺杂能增强配合物中Eu^(3+)的特征荧光,当铕与钇的摩尔比为7∶3时配合物的荧光强度最强。
A series of complexes（Eu（1-x）Yx）2L3 phen have been synthesized using succinic acid and1,10-phenanthroline as ligand.The structure and fluorescence properties of complexes were also characterized by infrared spectroscopy,fluorescence spectroscopy and DSC.The results showed that yttrium doping can enhance the characteristic fluorescence of Eu^3＋.The as-synthesized complexes exhibited highest fluorescence intensity when the ratio of europium to yttrium was 7∶3.
