| 摘 要： | 合成了不同摩尔比的苯基羧甲基亚砜高氯酸铽、铥异核配合物 ,对配合物进行了组成分析 ,确定了配合物组成为 (Tb1 -xTmx) L2 (ClO4 ) ·2H2 O(x=0 0 0 0～ 0 2 0 0 ,L=C6 H5SOCH2 COO- )。通过IR光谱及摩尔电导的测定推测了配位情况 ,溶解性实验表明配合物在乙醇、丙酮等极性溶剂中具有很高的溶解性。荧光光谱实验表明 :当 x =0 0 0 1～ 0 10 0时铥对铽的荧光均产生敏化增强效应 ,当x =0 0 0 1时敏化强度最大 ,可使Tb3+ 荧光强度增加 32 6 %。

| Abstract: | (Tb1-x Tmx).L2.(ClO4).2H2O(x = 0.000 to 0.200, L = C6H5SOCH2COO-) have been synthesized. The coordination compounds have been studied by means of composition analysis, molar conductivity, IR, and the condition of coordination have been inferred. In the fluorescent spectra it was found that Tm3+ has a strongly sensitization effect to the fluorescence of Tb3+. The fluorescent emission intensity of Terbium perchlorate with phenylcarboxymethyl sulfoxide coordination compounds would be enhanced by Tm3+ in mixing. Tm3+ has a sensitization to the fluorescence of Tb3+ in the ratio of Tb3+:Tm3+ = 0.999:0.001-0.900:0.100. In the solubility experiment it was found that the complexes have high solubility in ethanol. |
