摘　　要：通过溶液法将三种辛酰类氨基酸配体与钐离子结合成三种新型氨基酸钐(Ⅲ)配合物,分别简写为Sm(oct-ala)_(3)、Sm(oct-phe)_(3)、Sm(oct-ser)_(3)。使用元素分析、^(1)H NMR和FT-IR结果确定了钐配合物的化学式和配位方式,XRD衍射谱表明,配合物是长程无序的非晶态结构,通过TG-DTA研究了钐配合物的热学性能,此外还测试了钐配合物在常见有机试剂中的溶解度。测试了钐配合物的紫外-可见光吸收、荧光光谱和量子效率,结果表明,三种钐配合物均具有良好的光吸收和发光性能。使用点胶涂敷法将配合物粉末封装在LED中,在365 nm波长的灯芯激发下趋向白光,验证了由发射光谱计算得到的CIE色度图。Three kinds of new samarium(Ⅲ)complexes(abbr.Sm(oct-ala)_(3),Sm(oct-phe)_(3) and Sm(oct-ser)_(3))with octanoyl-aminocarboxylate ligands were prepared by chemical reaction method in methanol.The chemical formula and coordination mode of the complexes were determined by elemental analysis,^(1)H NMR and FT-IR.The XRD diffraction spectra determine that the complexes have long-range disorder amorphous structure.The thermal properties of the complexes were determined by TG-DTA.The solubility of the complexes in various organic reagents was also measured.The optical properties of the complexes were measured by UV-Vis absorption,fluorescence spectrum and quantum efficiency test.The results show that the three complexes have excellent light absorption and luminescence properties.Under the excitation light source of 365 nm,the powder of the complexes tend to be white.It conforms to the CIE chromaticity map which calculated from the emission spectrum.
