| 摘 要： | 合成了以柠檬酸为第一配体、1,10-菲咯啉为第二配体的单核稀土(Eu、Tb)配合物和Tb/Y、Eu/Y按不同比例混合的掺杂稀土配合物。采用红外光谱、紫外光谱、激发和发射光谱等对合成的配合物结构和荧光性能进行了表征。红外光谱表明稀土离子与第一、第二配体进行了配位,配合物的紫外吸收主要是配体的吸收,保持了π→π* 电子跃迁的特征。激发和发射光谱表明,不发光稀土离子Y3+的掺入能显著增强发光稀土离子的光发射强度。

| Abstract: | In my paper,the rare earth(Eu,Tb) complexes were synthesized with citric acid as the first ligand and 1,10-phenanthroline(phen) as the secondary ligand,ternary rare earth complexes with a series of different ratios of Eu/Y and Tb/Y were synthesized.The complexes synthesized were characterized by IR spectra,UV spectra and emission-excitation spectra.IR spectra and elemental analysis show that composition and structure of the complexes synthesized is the same as the data in accordance with a chemical formula,... |
