  • Stabilized quantum dot composite and method of making a stabilized quantum dot composite
    Patent number: 10879433
    Abstract: A stabilized quantum dot composite includes a plurality of luminescent semiconducting nanoparticles embedded in a matrix comprising an ionic metal oxide. A method of making a stabilized quantum dot composite includes forming a mixture comprising a plurality of luminescent semiconducting nanoparticles dispersed in an aqueous solution comprising an ionic metal oxide. The mixture is dried to form a stabilized quantum dot composite comprising the plurality of luminescent semiconducting nanoparticles embedded in a matrix comprising the ionic metal oxide.
    Type: Grant
    Filed: May 22, 2019
    Date of Patent: December 29, 2020
    Assignee: CREE, INC.
    Inventors: Kenneth Lotito, Ryan Gresback, Ceri Griffiths, Paul Fini
