苯甲酸-铕-铽配合物的荧光光谱研究

Study on the Fluorescence Spectra of Europium Benzoate Complexes

合成了苯甲酸－ 铕－ 铽和苯甲酸－ 铕－ 铽－ 镧系列固体配合物，研究了它们的荧光发射光谱。结果表明，Ｔｂ３＋ 对Ｅｕ３＋ 的荧光发射有很强的敏化作用，而Ｅｕ３＋ 对Ｔｂ３＋ 的荧光发射有很强的猝灭作用；但Ｅｕ３＋ 和Ｔｂ３＋ 的荧光发射峰的位置基本上保持不变。

A series of the mixed solid complexes of europium terbium benzoate and europium terbium lanthanum benzoate were synthesized.Their fluorescence spectra have been investigated.The results showed that the fluorescence emission of europium ions were greatly sensitized by terbium ions and those of terbium ions were strongly quenched by europium ions.But the peak positions of their emission spectra basically keep unchanged.
