Abstract
The present disclosure provides a method of preparing graphene quantum dots by intercalation of graphite nanoparticles and continuous exfoliation in an aqueous solution. The preparation method has a short process time and uses graphite nanoparticles of several nm as a reactant. Thus, graphene quantum dots prepared by the preparation method are uniform in size and shape with minimized defects and improved electrical properties.
