异核高氯酸钐、镝在二苯亚砜体系中的共发光

Columinescence of different nuclear perchlorate (Sm^(3+),Dy^(3+))with phenyl sulfoxide coordination compounds

合成了一系列异核高氯酸钐、镝二苯亚砜配合物 :SmxDy1-x(DPSO) 7(ClO4) (x =1 0 0 0 - 0 0 0 0 ,DPSO为二苯亚砜 )。测定了配合物的组成、IR谱、荧光激发和发射光谱。荧光发射光谱表明 :在二苯亚砜体系中S3 + m 对Dy3 + 的发光有明显的猝灭作用 ,而Dy3 + 对Sm3 + 的发光有较强的敏化作用。根据配合物的荧光光谱计算了(Sm3 + 、Dy3 + )及配体DPSO的有关能级 。

Sm xDy 1-x (DPSO) 7(ClO 4)(x=1 000～0 000,DPSO=the abbreviation to diphenyl sulfoxide)have been synthesized.The composition,excitation and emission spectra were studied.It was found that the fluorescent emission intensity of Sm 3+ was enhanced by Dy 3+ and the fluorescent emission intensity of Dy 3+ was quenched by Sm 3+ .In addition,the 4G 5/2 , 6H 7/2 , 6H 9/2 energy levels of Sm 3+ and 4F 9/2 , 6H 13/2 , 6H 11/2 energy levels of Dy 3+ and energy levels of ligand were calculated according to the fluorescent spectra result.In the mean time,the mechanism of enhancemention and quenching were studied.
