  • Method of synthesising nitride nanocrystals
    Patent number: 9938148
    Abstract: A method of producing nitride nanoparticles comprises reacting at least one organometallic compound, for example an alkyl metal, with at least one source of nitrogen. The reaction may involve one or more liquid phase organometallic compounds, or may involve one or more liquid phase organometallic compounds dissolved in a solvent or solvent mixture. The reaction constituents may be heated to a desired reaction temperature (for example in the range 40° C. to 300° C.).
    Type: Grant
    Filed: November 12, 2013
    Date of Patent: April 10, 2018
    Assignee: Sharp Kabushiki Kaisha
    Inventors: Alastair James Daniel Grundy, Peter Neil Taylor, Michael Alan Schreuder, Stewart Edward Hooper, Jonathan Heffernan

  • Preparation of nanoparticles with narrow luminescence
    Patent number: 8951439
    Abstract: A population of light-emissive nitride nanoparticles has a photoluminescence quantum yield of at least 10% and an emission spectrum having a full width at half maximum intensity (FWHM) of less than 100 nm. One suitable method of producing light-emissive nitride nanoparticles comprises a first stage of heating a reaction mixture consisting essentially of nanoparticle precursors in a solvent, the nanoparticle precursors including at least one metal-containing precursor and at least one first nitrogen-containing precursor, and maintaining the reaction mixture at a temperature to seed nanoparticle growth. It further comprises a second stage of adding at least one second nitrogen-containing precursor to the reaction mixture thereby to promote nanoparticle growth.
