  • Organic-inorganic complexes containing a luminescent rare earth-metal nanocluster and an antenna ligand, luminescent articles, and methods of making luminescent compositions
    Patent number: 9017573
    Abstract: Luminescent compositions are described comprising lanthanide-containing nanoclusters comprising lanthanide atoms bonded to at least one semimetal or transition metal via an oxygen or sulfur atom. Novel compositions include an antenna ligand complexed with the nanoclusters. The rare earth-metal nanoclusters are in the size range of 1 to 100 nm. Articles, such as solar cells, are described in which the nanoclusters (with or without antenna ligands) are dispersed in a polymer matrix. Novel methods of making luminescent films are also described.
