摘要
合成了不同摩尔比的苯基苯甲酰甲基亚砜高氯酸铕、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Eu1-xTmx(ClO4)3L5·2H2O(x=0.000～0.200,L=C6H5SOCH2COC6H5).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:微量铥的掺入即对铕的发光产生猝灭作用.
Five different proportional binuclear complexes (mided Eu^(3+) and Tm^(3+)) of rare earth perchlorate with phenyl-phenacyl sulfoxide were synthesized.Composition analysis suggestes that the complexes have the composition of Eu_(1-x)Tm_x(ClO_4)_3L_52H_2O (L=C_6H_5SOCH_2COC_6H_5,X=\{0.000\}~0.200) respectively.The IR spectra and the molar conductivities indicate the condition of coordination.The fluorescence spectra show that Tm^(3+) has a quenching effect on the fluorescence of Eu^(3+).
