Abstract：The excitation and emission spectra of seven Tb3+ complexes were measured and investigated, especially by comparing their fluorescence intensities. The effect of different ligands on the fluorescence intensity of Tb3+ was analyzed in terms of ligand structure, energy transfer and energies matching. The result indicates that ligands do not influence the positions of characteristic emission peaks of Tb3+,but the emission intensity. The research shows that the better the conjugative effect and rigidity of the ligand, the stronger the fluorescence intensity of the complex. In addition, binary acid strengthens the fluorescence intensity more efficiently than monoatomic acid. Eventually, the IR and Raman spectra of seven complexes of Tb were discussed.
