摘　　要：在无水乙醇中,合成了组成为RE(C5H8NS2)3(C12H8N2)(RE=La,Pr,Nd,Sm～Lu)的固态配合物。IR光谱表明配合物中稀土离子(RE3+)与吡咯烷二硫代氨基甲酸铵(APDC)中的硫原子和1,10 邻菲咯琳(o phen)中的氮原子均双齿配位;UV光谱显示配合物中o phen与稀土离子之间的能量传递是主要过程,配合物的最大吸收与o phen相比有微小的红移;FS光谱表明配合物Sm(C5H8NS2)3(C12H8N2)和Eu(C5H8NS2)3(C12H8N2)具有很强的荧光性质。The solid complexes RE(C_5H_8NS_2)_3(C_(12)H_8N_2) (RE=La, Pr, Nd, Sm～Lu) were synthesized in absolute ethanol, and were characterized by IR, UV and FS spectra. IR results reveal that the RE^(3+) coordinated with sulfur atoms of APDC and nitrogen atoms of o-phen. As for UV spectrum of the complexes, energy transfer between o-phen and RE^(3+) is the primary process, and the main absorption peaks show a slight red shift than that of o-phen; FS spectrum, as a comparison, the complexes Sm (C_5H_8NS_2)_3(C_(12)H_8N_2) and Eu(C_5H_8NS_2)_3(C_(12)H_8N_2) have stronger fluorescence character.
