苯基羧甲基亚砜体系中高氯酸铥对高氯酸铽的荧光增强效应研究

Fluorescence Enhancement Character of Terbium Perchlorate and Thulium Perchlorate with Phenylcarboxymethyl Sulfoxide Coordination Compounds

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 %。

(Tb1-xTmx) . L-2 . (ClO4) . 2H(2)O(x = 0.000 to 0.200, L = C6H5SOCH2COOO-) have been synthesized. The coordination compounds have been studied by means of I composition analysis, molar conductivity, IR, and the condition of coordination have been infered. 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.
