摘　　要：2,2’-联吡啶(bipy)、邻氨基苯基苯甲酸(HL)与稀土离子(RE=Tb,Eu,Sm,Nd)合成了固体稀土配合物。用元素分析、摩尔电导、紫外光谱、红外光谱、差热-热重分析和荧光光谱,对配合物的组成进行了确定和表征,并对TbL3和TbL3·bipy·3H2O的荧光性能进行了测试和讨论。TbL3·bipy·3H2O的荧光强度比TbL3的荧光强度强。The solid rare-earth complexes were synthesized using rare-earth ions （RE=Tb, Nd, Sm, La） reacting with ortho-amino phenylbenzoic acid （L） and 2,2＇-bipyridine （bipy）. Their compositions were confirmed and the spectral properties were characterized by element analysis, infrared and ultraviolet absorption spectra, and DTA-TGA. The fluorescent properties of complexes TbL3 and TbL3· bipy · 3H2O were also measured and discussed. The result shows that the fluorescence intensity of TbL3 · bipy· 3H2O is stronger than that of TbL3.
