合成了高氯酸镝铕（Ⅲ）二苯亚砜Ｄｙ１－ ｘ Ｅｕｘ （ＤＰＳＯ）７ （ＣｌＯ４）３ （ｘ＝ １．０００～０．０００）一系列固体配合物．测定了配合物的组成及荧光激发和发射光谱，发现镝（Ⅲ）对铕（Ⅲ）的发光有猝灭作用，铕（Ⅲ）对镝（Ⅲ）的发光也有猝灭作用．同时研究了Ｄｙ３＋ 、Ｅｕ３＋ 相互猝灭的浓度范围，并根据实验结果计算了配体Ｓ１ 能级以及Ｄｙ３＋ 的有关能级．
A series of solid complexes of Dy1- x Eux (DPSO) 7 (ClO4) 3 (x = 1.000 ~ 0.000) were synthesized. The composition, fluorescence excitation and emission spectra of the complexes were determined. It was found that dysprosium (Ⅲ) quenched the luminescence of europium (Ⅲ) and quenched the emission of dysprosium (Ⅲ) by europium (Ⅲ). At the same time, the concentration range of quenching of Dy3 + and Eu3 + was studied. The energy levels of ligand S1 and Dy3 + were also calculated according to the experimental results.
