  Abstract


A ?-hydroxyketone 5-fluoro-2-hydroxyacetophenone (FHAP) was employed to synthesize the green light emitting terbium complex. The various techniques such as CHN elemental analysis, IR, NMR, UV-visible and photoluminescence (PL) spectroscopy were used to characterize the ligand and complex. In the emission spectra, three peaks at 491 nm, 545 nm and 592 nm observed which were assigned to the 5D4?7F6, 5D4?7F5 and 5D4?7F4 transitions of the terbium(III) metal ion. The electric dipole 5D4?7F5 transition dominated in the emission spectra which was sensitive to the chemical environment of the terbium ion and controlled the green luminescent color of the complex. The CIE color coordinates (x and y) fall in the green region of the chromaticity diagram. The optoelectronic properties demonstrated that the terbium(III) complex can be applied as luminescent component in display devices.
