In the past 30 years, research on rare-earth complexes has developed, and it is now known that complexation of rare-earths with a ligand with high absorbance, called β-diketone, results in strong luminescence. In this study, the main ligand with high absorption and four kinds of auxiliary ligands are introduced and the complexes are compared and investigated.
