高氯酸镝、高氯酸铕在二苯亚砜体系中的共发光

Columinescence of Dysprosium Perchlorate,Europium Perchlorate with Diphenyl Sulfoxide Coordination Compounds

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．

Dy 1-x Eu x (DPSO) 7(ClO 4) 3( x =1.000~0.000)(DPSO as the abbreviation to diphenyl sulfoxide) have been synthesized.Their composition,Excitation and emission spectra have been studied.In result,it was found that the fluorescence of Eu 3+ ion was quenched by Dy 3+ ion and the fluorescence of Dy 3+ ion was also quenched by Eu 3+ ion.At the same time,the interquenching concentration ranges of the fluorescence for Dy 3+ and Eu 3+ were discussed.The 4F 9/2 , 6H J/2 (J=13,11) energy levels of Dy 3+ and energy levels of ligand have been calculated according to the fluorescence spectra results.
