摘要
合成了以TTFA、1,10-Phen为第一和第二配体的系列铕和钐、铽(用Re表示钐、铕)双核稀土有机配合物Re1-xTbx(TTFA)3Phen,测试了不同掺杂浓度的各个配合物的紫外吸收光谱和荧光光谱。由紫外吸收光谱可以看出,稀土有机配合物的吸收峰主要来自有机配体。讨论了配合物的传能机理。荧光光谱表明,铽离子对钐离子有敏化效应,铽离子对铕离子有强烈的敏化效应。
A series of rare earth complexes of Eu3 ＋ and Sm3 ＋ ion with TTFA（ as the first ligand ） and 1, 10 - Phen （ as the secondary ligand） dopped with different concentration of Tb3 ＋ have been synthesized. The UV absorption spectra and fluorescence spectra of the binuclear complexes Re1-xThx（TTFA）3 Phen （ Re is Sm or Eu） have been measured. UV absorption spectra indicated that the absorption energy of complexes mostly come from the organic ligands （TTTA and 1, 10 - Phen）. The energy transfer mechanism in the complexes has been discussed. The fluorescence spectra indicated that not only the organic ligands but also the Tb3＋ ion can transfer the absorbed energy to the central Eu3＋ ion and Sm3＋ ion in the complexes, We have found that Tb3＋ ion has a strong sensitization effect on the fluorescence orooerties of Eu3＋ ion, also, Tb 3ion has a strong sensitization effect on the fluorescence orooerties of Eu3＋ ion.
