Patent number: 9017573Abstract: 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.Type: GrantFiled: August 19, 2009Date of Patent: April 28, 2015Assignee: Batlelle Japan CorporationInventors: Steven M. Risser, Vincent McGinniss, David W. Nippa, Paul Edward Burrows, Asanga B. Padmaperuma, Sambhu N. Kundu, Hiroshi Mataki

Patent number: 6365270Abstract: A multicolor organic light emitting device employs vertically stacked layers of double heterostructure devices which are fabricated from organic compounds. The vertical stacked structure is formed on a glass base having a transparent coating of ITO or similar metal to provide a substrate. Deposited on the substrate is the vertical stacked arrangement of three double heterostructure devices, each fabricated from a suitable organic material. Stacking is implemented such that the double heterostructure with the longest wavelength is on the top of the stack. This constitutes the device emitting red light on the top with the device having the shortest wavelength, namely, the device emitting blue light, on the bottom of the stack. Located between the red and blue device structures is the green device structure.Type: GrantFiled: December 9, 1999Date of Patent: April 2, 2002Assignee: The Trustees of Princeton UniversityInventors: Stephen Ross Forrest, Mark Edward Thompson, Paul Edward Burrows, Linda Susan Sapochak, Dennis Matthew McCarty
