  • Magnetic nanoparticles
    Patent number: 9330821
    Abstract: Methods for preparing magnetic nanoparticles comprising metal, metal carbide, metal nitride, metal sulfide, metal phosphide, metal oxide or a mixture thereof are disclosed. Methods for preparing magnetic nanoparticles having a core comprising metal, metal carbide, metal nitride, metal sulfide, metal phosphide, or a mixture thereof and a metal oxide shell are also disclosed. The methods comprise the solution-phase decomposition of a precursor at elevated temperature then exposure of the reaction mixture to an oxidizing medium, such as air.
    Type: Grant

  • Methods of Forming Nanoparticles
    Publication number: 20100139455
    Abstract: The present invention provides a method for preparing nanoparticles of group IV elements, particularly nanoparticles of Si, Ge and Sn, and binary and ternary alloys of these elements. The method comprises the solution-phase decomposition of one or more group IV metal precursors at elevated temperature and under an inert atmosphere at atmospheric pressure, using a decomposition-promoting reagent. A surface-bonding agent is added to the reaction mixture to form an organic layer surrounding the nanoparticles and prevent aggregation.
