摘　　要：在乙醇和水的混合溶剂中,合成了均苯四甲酸铽发光配合物。通过元素分析、化学分析、红外光谱、热分析等确定其化学组成为Tb(HL)·5H2O。X射线衍射分析表明配合物为晶体物质,扫描电镜照片结果表明配合物为棒状物质,晶粒大小10μm～20μm,荧光光谱分析表明配合物在紫外光的激发下发出铽的特征荧光。The luminescent chelate of Tb-pyromellitic acid was synthesized in the alcohol and water mixed solvent. The element analysis, the chemical analysis and FTIR results showed that the chelate is Tb(HL)·5H_2O.Thermal analysis indicated that the chelate has better stability at temperature of 530℃. XRD pattern indicated that the chelate is crystal, and SEM photograph showed that the chelate is bar shape and the grain size is 10μm^20μm. PL spectra showed that the chelate emitted the character fluorescence of Tb(Ⅲ) under ultraviolet light.
