合成了稀土(Eu~(3+)和Tb~(3+))与二苯甲酰甲烷(DBM)、2,2′-联吡啶(Dipy)的一系列稀土配合物Eu_xTb_(1-x)(DBM)_3Dipy.元素分析和红外分析确定了配合物的组成,荧光光谱研究了荧光性质.铽掺入配合物后,铽能极大地增强铕的特征荧光,铽对铕配合物的发光有协同作用.在该系列配合物中,不仅有机配体可以将吸收的能量传递给发光的铕离子使其发光,而且铽离子也可将其吸收的能量通过分子内能量传递给铕离子.
閤成瞭稀土(Eu~(3+)和Tb~(3+))與二苯甲酰甲烷(DBM)、2,2′-聯吡啶(Dipy)的一繫列稀土配閤物Eu_xTb_(1-x)(DBM)_3Dipy.元素分析和紅外分析確定瞭配閤物的組成,熒光光譜研究瞭熒光性質.鋱摻入配閤物後,鋱能極大地增彊銪的特徵熒光,鋱對銪配閤物的髮光有協同作用.在該繫列配閤物中,不僅有機配體可以將吸收的能量傳遞給髮光的銪離子使其髮光,而且鋱離子也可將其吸收的能量通過分子內能量傳遞給銪離子.

A series of complex Eu_xTb_(1-x)(DBM)_3Dipy were synthesized in anhydrous alcohol with dibenzoyl methane(DBM)and 2,2-dipyridyl(Dipy).The compounds were characterized by elemental analysis and IR spectra and fluorescent properties were studied by fluorescent spectra.The fluorescence emission intensity of Eu~(3+) would be enhanced by Tb~(3+) in the mixed complexes(Tb~(3+) was mixed).The fluorescence spectra of the complexes indicated that the fluorescence emission intensity of Eu~(3+) was sensitized by Tb~(3+) in the complexes.Not only the ligands but also the terbium complex can transfer the absorbed energy to Eu~(3+) in the complexes.
