A series of luminescent ternary terbium complexes based on fluorinated ligand 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione (TFNB) and other auxiliary ligands were synthesized and explored. Optical and photophysical characteristics of complexes were examined spectroscopically. Thermal and electrochemical behavior of complexes is also reported. In emission spectra of complexes, four characteristic peaks of Tb3+ ion at 492 nm, 548 nm, 586 nm and 615 nm accredited to 5D4 → 7FJ (J = 6–3) transitions appeared upon excitation in UV region. Most intense peak at 548 nm is accountable for bright green emission of ternary complexes. Color purity and CIE parameters also suggest the green luminous behavior of complexes. Our investigation has revealed that the synthesized complexes could be used in preparing lighting system, OLEDs and display devices owing to their luminescent characteristics.
