An analysis of luminous mechanism of rare earth hybrid complex with Ce3+ ion by the DV-Xα method

In recent years, rare earth compounds with Ce3+ ion have reported as light-emitting materials due to photoluminescence. But Ce3+ ion luminous mechanism has not yet particularly reported until now on account of disparate ligands. In this report, results of study manifested it would possible make complicated, which coordinated by ligands upon π conjugation. In this study, several fluorescent compounds as well as non-fluorescent compounds have synthesized by solution method, which coordinated by common organic ligands with π conjugation, such as acetylacetonato(acac), oxalate(ox), 2,2′-bipyridine(bpy), 1,10-phenanthroline(phen). It have been made clear about Luminous mechanism by means of experimentation compare to molecular orbital method.
