Co-luminescence of ions and molecules in nanoparticles of metal complexes

The features of co-luminescence (sensitized luminescence) of lanthanide ions and dye molecules inserted in nanoparticles of complexes formed by trivalent metals with β-diketones are discussed. The mechanisms of energy transfer in these nanoparticles that lead to sensitization of Ln³⁺ ion luminescence and dye molecule fluorescence are considered. It is shown that the process of nanoparticle formation and their morphology in aqueous solutions can be studied by analyzing the mechanism of their co-luminescence and co-fluorescence. Examples of chemical, biological and medicinal applications of nanoparticles containing lanthanide ions and dye molecules with enhanced luminescence brightness are given.
