摘　　要：从1,3,5-均苯三甲酸出发,制备了一系列铽及镧铽均苯三甲酸发光配合物LaxTb1-x(BTC).nH2O(x=0,0.1~0.5,0.8).通过红外光谱、元素分析确定了其组成,并研究了其配合物荧光光谱.结果表明:不发光的La3+对发光的Tb3+的荧光强度有明显增强作用,当n(La3+)∶n(Tb3+)=0.3∶0.7时,荧光强度达到最大值.A series of complexes LaxTb1 - x （BTC）·n H2O（ x = 0,0.1 - 0.5,0.8 ） were synthesized and the trimesic acid （1,3,5-benzenetricarboxylate, H3BTC, C9H3O6 ） was used in ligand. Their compositions were defined by IR spectra and element analysis, and their luminescent spectra were studied. The results show that the emission intensity of Tb^3＋ were greatly enhanced by La^3＋ in the complexes, and the intensity is the greatest when n（La^3＋ ）： n（Tb^3＋） =0.3：0.7.
