The lanthanide complex of europium ion with BAA (2-benzoylacetanilide) was successfully synthesized and their photoluminescence features were investigated. The BAA and its complex were characterized by various techniques such as IR, NMR, CHN elemental analysis, UV-visible and photoluminescence spectroscopy. The complex exhibited the luminescence of the europium(III) ion in visible region ascribed to the efficient energy transfer from ligand to the central metal. Upon excitation at 395 nm, the emission spectra of complex showed characteristic peaks of europium ion at 580 nm, 591 nm, 613 nm and 651 nm assigned to 5D0?7F0, 5D0?7F1, 5D0?7F2 and 5D0?7F3 electronic transitions, which originate due to transition between excited 5D0 state and ground 7Fj (j = 0, 1, 2 and 3) state of europium ion. The color coordinates of the complex located in the red region of the chromaticity diagram. These results suggested that the complex can be potential applied for display devices.
