摘　　要：分别以邻氯苯甲酸和间氟苯甲酸为第1配体,1,10-邻菲啰啉为第2配体,合成了4种Tb(Ⅲ),Eu(Ⅲ)的三元配合物和8种分别掺杂Gd(Ⅲ),Y(Ⅲ)的四元配合物.在室温下测得了各配合物的激发和荧光发射光谱,讨论了配合物中的掺杂离子对配合物发光性能的影响,结果表明Gd(Ⅲ),Y(Ⅲ)对配合物中Tb(Ⅲ),Eu(Ⅲ)的发光均有敏化作用.Four ternary complexes of terbium （europium） with o-chlorobenzolc acid （m -fluorobenzoic acid） as the first ligand and the 1,10-phenanthroline as the second ligand were synthesized. Eight quarternary complexes doped with Gd（ Ⅲ ） or Y（ Ⅲ ） were also synthesized. The excitation and luminescence spectra of all the complexes were carried out at room temperature, and the relationship between the fluorescence intensity of complexes and the doped metal ions were discussed. The results indicate that the doped Gd（ Ⅲ ） or Y（ Ⅲ ） ions could obviously sensitize the fluorescence radiations of Tb（Ⅲ） and Eu（Ⅲ） ions.
