摘要
本文测量了１２个稀土及钇（３价离子）苯多羧酸和杂环羧酸固体配合物的激发光谱和荧光光谱。讨论了不同配体对同一稀土离子发光影响和同一配体对不同稀土离子发光作用。结果指出苯多羧酸配体对Ｔｂ￣（３＋）、Ｅｕ￣（３＋）等四个稀土离于有较明显的能量传递作用。这作用与镧系离子间呈现双峰变化关系。
The excitation and fluorescence spectra of 12 kinds of rare earth benzene polycar-boxylic and heterocycle carboxylic acid complexes have been measured.The influence on lumines-cence behaviour of same rare earth ion from different ligand and the action of same ligand to lumi-nescence of various rare earth ions were discussed. The results show that there are energy transfer action evidently from benzene polycarboxylic acid ligand to Tb￣(3+)、Eu￣(3+)、Dy￣(3+) and Sm￣(3+) ions. The magnitude of energy transfer presents the double peak effect to lanthanide.
