Four Tb(III) ternary complexes with 1-phenyl-3-methyl-4-isobutyrylpyrazol-5-one (HPMIBP) or 1-phenyl-3-methyl-4-benzoylpyrazol-5-one (HPMBP) as the ligand: Tb(PMIBP)3.2H2O(A1), Tb(PMIBP)3.bpy(A2), Tb(PMBP)3.2H2O(B1) and Tb(PMBP)3.bpy(B2) (where bpy=2, 2'-dipyridyl), were ynthesized and identified by elemental analysis. They were characterized by UV-Vis, FT-IR spectra and DTA-TG analysis. Their luminescence from both the solid state and solutions were studied and their fluorescence lifetimes were measured from solutions. Results show that the fluorescence intensities of A1 and A2 are three orders magnitude stronger than those for B1 or B2; besides, the fluorescence intensity of A2 and B2 are relatively stronger than those of A1 and B1. The solvents strongly effect on the fluorescence performances of the complexes both in fluorescence intensity and lifetime.
