| 摘 要： | 在乙醇和水的混合溶剂中,合成了稀土铕 Eu(III)]-苯甲酸HL]二元发光配合物.通过元素分析、等离子体原子发射光谱分析(ICP-AFS)、红外光谱分析(FT-IR),推测其化学组成为EuL1.5(OH)1.5.X线衍射分析(XRD)结果表明,配合物是与配体结构完全不同的新的晶体物质.扫描电镜分析(SEM)结果表明苯甲酸铕配合物为微小粒子,晶粒大小约为50～100 nm.热分析(TG-DTA)结果表明,配合物在470 ℃以下稳定性较好.荧光光谱分析(PL)结果表明,配合物在紫外光的激发下发出铕的特征荧光.

| Abstract: | The luminescent complex of the rare earth Eu3+-benzoic acid was synthesized in the alcohol and water mixed solvent.The elemental analysis,plasma atomic emission spectra,infrared spectra were measured the composition of obtained samples and the chemical composition deduced is EuL1.5(OH)1.5.XRD patterns showed that the obtained coordination compound is new crystal different from that of the ligand.SEM photograph indicated that coordination compound is sphere shape and the grain size is about 50~100 nm.Thermal... |
