中文摘要：

以2-甲基苯甲酸（2-MBA）为第一配体、1,10-邻菲罗啉（phen）为第二配体,制备了三元铽配合物Tb（2-MBA）3phen和二元铽配合物Tb（2-MBA）3·2H2O,并利用元素分析、红外光谱、紫外光谱、荧光光谱和荧光寿命对二者的结构与性能进行分析表征。研究结果表明：三元铽配合物Tb（2-MBA）3phen的荧光发射强度要强于二元铽配合物Tb（2-MBA）3·2H2O,而二者的荧光寿命恰好相反,三元铽配合物Tb（2-MBA）3phen的荧光寿命短于二元铽配合物Tb（2-MBA）3·2H2O。热重分析表明Tb（2-MBA）3·2H2O的热分解温度要远高于Tb（2-MBA）3phen。

英文摘要：

Using 2-methylbenzoic acid（ 2-MBA） as the first ligand,and phenanthroline（ phen） as the second ligand,ternary terbium Tb（ 2-MBA）3phen and binary terbium Tb（ 2-MBA）3·2H2O were prepared. The performance of the two kinds of terbium complexes was analyzed by elemental analysis,IR spectra,UV-vis spectra,fluorescence spectra and fluorescence lifetime. The results showed that the fluorescence emission intensity of Tb（ 2-MBA）3phen was stronger than that of Tb（ 2-MBA）3·2H2O,and the fluorescence lifetime of them was on the contrary. The fluorescence lifetime of Tb（ 2-MBA）3phen was shorter than that of Tb（ 2-MBA）3·2H2O. TG results showed that the thermal decomposition temperature of Tb（ 2-MBA）3·2H2O was much higher than that of Tb（ 2-MBA）3phen.
