  • Zinc chalcogenides, doped zinc chalcogenides, and methods of making
    Patent number: 8801972
    Abstract: A process of preparing a zinc chalcogenide includes providing a solution of 8-hydroxyquinoline; a zinc precursor; and a reaction solvent; isolating a precipitate from the solution; and calcining the precipitate to form the zinc chalcogenide. Additionally, a polymer composite may include a polymer, bis(8-hydroxyquinolinato)zinc, and elemental sulfur or bis(8-hydroxyquinolinato)zM, wherein M is a metal ion and the value of z is equivalent to the oxidation state of the metal ion.
    Type: Grant
    Filed: February 10, 2012
    Date of Patent: August 12, 2014
    Assignee: Indian Institute of Technology Kanpur
    Inventor: S. Sundar Manoharan
  • Doped aluminum oxides
    Patent number: 8524178
    Abstract: A process of preparing a doped aluminum oxide, includes providing a solution comprising 8-hydroxyquinoline; an aluminum precursor; a dopant precursor, and a reaction solvent; isolating a precipitate from the solution; and calcining the precipitate to form the doped aluminum oxide. Compositions may be prepared which include tris(8-hydroxyquinolinato) aluminum and (8-hydroxyquinolinato)zM, wherein M is a metal ion and the value of z is equivalent to the oxidation state of the metal ion.
