Abstract：Seven ternary complexes of Tb(Ⅲ) were synthesized with benzoic acid(BA), o-, m-, p-methylbenzoic acid (o-MBA, m-MBA, p-MBA), and o-, m-, p-methoxybenzoic acid(o-MOBA, m-MOBA, p-MOBA) as the first ligand, and 1,10-phenanthroline(phen) as the second ligand. The content of C, H and N were measured by using a Flash-EA model 1112 elemental analyzer. Excitation and luminescence spectra of the title solid complexes were recorded by using a Hitachi F-4500 fluorescence spectrophotometer at room temperature. The effects of different varieties and different positions of replacing benzoic acid as the first ligand on fluorescence properties of the ternary complexes of terbium were discussed. The results indicated that the intensity of 5D4→7F6(489 nm) and 5D4→7F5(545 nm) of substituting benzoic acid complexes was stronger than benzoic acid. Three ternary complexes of Tb(Ⅲ) with o-, m-, p-methylbenzoic acid showed emission intensity in the consecution: Tb(o-MBA)3phen＜Tb(m-MBA)3phen·H2O＜Tb(p-MBA)3phen. However，for the complexes with o-, m-, p-methoxybenzoic acid as the first ligand: Tb(o-MOBA)3phen·H2O＞Tb(m-MOBA)3phen·H2O＞Tb(p-MOBA)3phen.
