Abstract
Five samarium complexes are synthesized with main ligand ethyl(4-methylbenzoyl) acetate (EMB) and secondary ligands 4,4′-dimethyl-2,2′-bipyridyl; 2,2′-bipyridyl; 1,10-phenanthroline and bathophenanthroline. The synthesized complexes are investigated by employing different techniques, including elemental analysis, EDX, FT-IR, NMR, TG/DTG, DR, and UV–vis absorption spectroscopy. The investigation of optical features of complexes helps to analyze their photoluminescent features. The characteristic peaks of samarium complexes under excitation of UV light are positioned at 568, 605, 650, and 693nm, and the peak responsible for vermilion emission is located at 605nm which is an intense one. Further, chromaticity coordinates, color purity, and correlated color temperature are calculated to explore vermilion color and the nature of the light of complexes. The decay curve, HOMO-LUMO energy gap, refractive index, and energy transfer mechanism are also discussed in present work.
