合成并表征了六种不同掺杂比例稀土高氯酸铕掺铥与对甲苯基苯乙烯基亚砜的固态配合物.经元素分析确定了配合物的组成为:(EuxTm1-x) (ClO4)3*L7(x=1.000,0.999,0.995,0.990,0.950,0.900; L= C6H5CH=CHSOC6H4CH3).配合物的红外光谱表明,配体通过亚砜基氧原子与稀土离子配位,烯键未参与配位.在丙酮溶液中测定的摩尔电导率表明,配合物为1∶2型电解质,三个 ClO4-无机抗衡阴离子,其中一个在内界,两个在外界.配合物的荧光发射光谱中出现了比磁偶极跃迁(5D0→7F1)强的电偶极跃迁(5D0→7F2),表明配合物不存在反演中心.掺杂配合物的荧光光谱表明,将千分之一的铥掺入后,铕离子的发光增强增加到111%.
