实验合成了邻苯二甲酸２，２′联吡啶混配稀土（铕、铽）配合物．在 ３２３ ｎｍ 紫外光激发下，测定了这些配合物的荧光．结果表明，铕、铽之间存在强相互作用．铽对铕的荧光强度有较强的敏化作用，而铕对铽有较强的猝灭作用，但其荧光发射峰位置基本不变．元素分析和热分析确定了配合物的化学组成为 Ｒｅ２ Ｌ３ Ｌ′·５ Ｈ２ Ｏ（ Ｌ＝ 邻苯二甲酸根， Ｌ′＝ ２，２′联吡啶）．红外光谱分析表明，邻苯二甲酸根和联吡啶均与稀土离子配位 Experimental synthesis of phthalic acid  2,2 ’bipyridine mixed rare earth (europium, terbium) complexes. Fluorescence of these complexes was measured at 323 nm UV excitation. The results show that there is a strong interaction between europium and terbium. Terbium has a strong sensitizing effect on the fluorescence intensity of europium, while europium has a strong quenching effect on terbium, but its fluorescence emission peak position remains basically unchanged. Elemental analysis and thermal analysis confirmed that the chemical composition of the complex was Re2 L3 L’.5H 2 O (L = phthalate, L ’= 2,2’ bipyridyl). Infrared spectroscopy showed that both phthalate and bipyridine were coordinated with rare earth ions
