  • Group III-V/Zinc chalcogenide alloyed semiconductor quantum dots
    Patent number: 10351767
    Abstract: A scalable method for the manufacture of narrow, bright, monodisperse, photo-luminescent quantum dots prepared in the presence of a Group II-VI molecular seeding cluster fabricated in situ from a zinc salt and a thiol or selenol compound. Exemplary quantum dots have a core containing indium, phosphorus, zinc and either sulfur or selenium.
    Type: Grant
    Filed: September 26, 2016
    Date of Patent: July 16, 2019
    Assignee: Nanoco Technologies Ltd.
    Inventors: Steven Daniels, James Harris, Paul Glarvey, Katherine Orchard, Arun Narayanaswamy
