| 摘 要： | 合成了高氯酸镝铕（Ⅲ）二苯亚砜Ｄｙ１－ｘＥｕｘ（ＤＰＳＯ）η（ＤＰＳＯ）η（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）和铕（Ⅲ）的姚有猝灭作用，铕（Ⅲ）对镝（Ⅲ）的发光也有猝灭作用，同时研究了Ｄｙ＾３＋、Ｅｕ＾３＋相互猝灭的浓度范围，并根据实验结果了配体Ｓ１能级以及Ｄｙ＾３＋的有关能级

| Abstract: | 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. |
