A series of heteroleptic luminescent europium moieties based on 1,10-phenanthroline and its derivatives were synthesized and studied for their photophysical characteristics through theoretical and experimental methods. The results showed that these complexes exhibited good quantum efficiency and emission properties, making them suitable for the design of various display devices.
We have synthesized a series of heteroleptic luminescent europium moieties based on 1,10-phenanthroline and its derivatives (L) namely Eu(BAP)(3)L; BAP = 2-benzoylacetophenone. The structural inspection of complexes was done by several spectroscopic techniques. Energy band gap values of complexes lie in region of semiconductors. Metal-ligand interaction results a notable effect on the eta (quantum efficiency) and omega(2) (JO parameters) of the prepared complexes. A detailed explanation about photophysical characteristics of the complexes was studied via theoretical and experimental methods. With the help of LUMPAC, theoretical photophysical properties were calculated and discovered to be in good concurrence with experimental values. The hypersensitive electric dipole peak positioned at 612 nm (D-5(0)-> F-7(2)) is reasonable for the red emission. The color coordinates are also situated in the red region of CIE triangle. Therefore, these efficient materials could be utilized as red emanating material in designing various display devices.
