摘　　要：在乙醇和水的混合溶剂中合成了均苯四甲酸(H4L)铕发光配合物。通过元素、化学分析、红外光谱确定其化学组成为Eu4/3L·7H2O。热分析表明,配合物在530℃以下稳定性较好,X射线衍射结果表明,配合物为晶体物质,扫描电镜照片表明配合物为块状物质,晶粒10μm-20μm,荧光光谱分析表明配合物在紫外光的激发下发出铕的特征荧光。Europium-pyromellitic acid luminescent chelate was synthesized in the mixed alcohol and water solvent. According to the element analysis, chemical analysis and FTIR results, it is determined that the chelate is Eu4/3L center dot 7H(2)O. Thermal analysis indicated that the chelate has better stability under the temperature of 530 degrees C. XRD pattern showed that the chelate is crystal. SEM photograph showed that the chelate is in block shape and the grain size is 10 mu m similar to 20 mu m. PL spectra showed that the chelate emitts the character fluorescence of Eu under ultraviolet light.
