摘要
在乙醇溶剂中合成了邻溴苯甲酸钐、铕、铽及镝四种稀土配合物。进行了元素分析、电导测定、紫外光谱分析、红外光谱分析及荧光光谱分析。结果表明,配合物的组成为REL_3,配体与稀土离子以共价键结合,EuL_3和TbL_3配合物能发出强的特征荧光,SmL_3和DyL_3荧光较弱。
The four solid complexes of o-bromobenzoic acid with rare-earth ions, (namely Sm^(3+), Eu^(3+), Tb^(3+) and Dy^(3+)) have been synthesized in ethanol. Their UV and IR absorption spectra as well as luminescence spectra were measured.
