Chromophoric 1,3-diketone ligand was used to prepare novel ternary complexes of terbium with differently substituted 2,2′-bipyridines as auxiliary ligands. These prepared complexes were thoroughly studied with the help of numerous spectroscopic techniques. IR spectral anal. suggested the coordination of diketone and ancillary ligand to the Tb(III) ion through oxygen and nitrogen atom, resp. Photoluminescence emission spectra of complexes have displayed only characteristic peaks of Tb3+ ion suggesting the efficient sensitization of metal ion by chromophoric ligands. Emission spectra of all complexes have displayed the ligand sensitized green emission due to the 5D4→7F5 transition situated at ∼548 nm. Colorimetric study and color purity of complexes reveal the green luminous character of synthesized complexes. Thermogravimetric measurements revealed the thermal stability of the complexes. Optical and electronic band gaps are in good agreement with each other that shows their importance as semiconductor material. These trivalent complexes of terbium could be used as the green component in displays and light emissive materials.
