  • Process and apparatus for forming nanoparticles using radiofrequency plasmas
    Patent number: 8016944
    Abstract: Methods and apparatus for producing nanoparticles, including single-crystal semiconductor nanoparticles, are provided. The methods include the step of generating a constricted radiofrequency plasma in the presence of a precursor gas containing precursor molecules to form nanoparticles. Single-crystal semiconductor nanoparticles, including photoluminescent silicon nanoparticles, having diameters of no more than 10 nm may be fabricated in accordance with the methods.
    Type: Grant
    Filed: November 3, 2008
    Date of Patent: September 13, 2011
    Assignee: Regents of the University of Minnesota
    Inventors: Uwe Kortshagen, Elijah J. Thimsen, Lorenzo Mangolini, Ameya Bapat, David Jurbergs
