  • Graphene quantum dots with different types and method for obtaining each of different types of graphene quantum dots
    Patent number: 10435301
    Abstract: The present application provides a method for producing a graphene quantum dot using thermal plasma, comprising injecting a carbon source into a thermal plasma jet to pyrolyze the carbon source so as to form a carbon atomic beam and allowing the carbon atomic beam to flow in a tube connected to an anode to produce a graphene quantum dot. The present application also provides an isolated graphene quantum dot from different types of graphene quantum dots and method for obtaining each of an isolated graphene quantum dot from different types of graphene quantum dots.
    Type: Grant
    Filed: January 27, 2016
    Date of Patent: October 8, 2019
    Assignee: SEOUL NATIONAL UNIVERSITY R&DB FOUNDATION
    Inventors: Jung Sang Suh, Juhan Kim, Myung Woo Lee
