Abstract
A series of single-molecule dysprosium (Dy 3+) complexes consisting of b diketonate ligands, as water-containing complexes, and the auxiliary triphenylphosphine oxide (tppo)ligand as water free complexes were investigated as potential white light emitters. The coordination environment and choice of the ligands play an important role in the behavior of the yellow and blue emission of the Dy 3+ complexes based on the sensitization efficiency of the Dy 3+ ion by the ligands. By introducing the auxiliary tppo ligand in the complex, the relative intensity of the Dy 3+ emission increases due to a more efficient sensitization of the Dy 3+ ion.
