在苯基羧甲基亚砜体系中高氯酸铒对高氯酸铽的荧光增强效应

Fluorescence Enhancing Effect of Erbium Perchlorate to TerbiumPerchlora te in Phenylcarboxymethyl Sulfoxide

合成了不同摩尔比的苯基羧甲基亚砜高氯酸铽、铒异核配合物,对配合物进行了组成分析,确定了配合物组成为Tb1-xErxL2ClO4·2H2O(x=0.000～0.200,L=C6H5SOCH2COO-)。通过IR光谱的测定以及摩尔电导推测了配位情况。荧光光谱实验表明:当x=0.001～0.010时铒对铽的荧光均产生敏化增强效应,当x=0.001时敏化强度最大,可使Tb3+荧光强度增加142%。
