Abstract
We have successfully synthesized Eu-based luminophores promising for inkjet printing with almost 100% efficiency of energy transfer from ligands to the lanthanide ion. The luminophores with β-diketonate ligands are characterized by means of optical spectroscopy. We reveal the impact of different types of β-diketonates on the quantum yield of luminescence and determine a β-diketonate complex exhibiting the highest luminescence quantum yield and promising for organic light-emitting diode (OLED) applications. We discuss the reasons for decreasing quantum efficiencies of other types of investigated ligands.
