Abstract:	New tris(3-phenyl-4-aroyl-5-isoxazolonate)terbium(III) complexes have been synthesized and characterized by various spectroscopic techniques. Due to an efficient energy transfer from the heterocyclic beta-cliketonate ligand to the central Tb3+, these complexes show a strong emission corresponding to (Tb3+5D4-FJ)-F-7(J = 6, 5, 4, 3) transitions, with D-5(4)-F-7(5) (545 nm) green emission as the most prominent one. The overall quantum yields and luminescent lifetimes of these complexes were found to be promising as compared to previously reported terbium-1-phenyl-3-methyl-4-acyl-5-pyrazolonate complexes.
