Description:
Two binary and ternary complexes of Terbium with N-HPA and Bipy (N-HPA: N-phenylanthranilic acid, Bipy: 2,2′-bipyridine ) were synthesized, and its structure was characterised by elemental analysis, UV and IR spectra. The effect of the second ligand on the fluorescence propertyof the complex was studied. The result proved that the fluorescence intensity of the binary terbium N-HPA complex was rather weak, but the addition of the second ligand Bipy could effectively increase luminescence intensity of terbium ions. The ternary complex of Tb(NPA) 3 (Bipy) (NPA: radical of N-HPA by removal of one H atom) has good fluorescence property. Tb(NPA) 3 (Bipy) 2 is a promising fluorescent material, which widely used in optoelectronics engineering and technology.
