▎ 摘　　要

NOVELTY - Manufacture of graphene quantum dots involves introducing (S100) a carbon-based layered structure into a reactor containing a solvent, forming (S200) an interlayer insert composite by inserting an interlayer insert between each layer of the carbon-based layer structure, placing (S300) the interlayer composite on a substrate, heat-treating to weaken the interlayer attractive force of the interlayer composite, and exfoliating (S400) the intercalation composite by applying a voltage to the substrate. USE - Manufacture of graphene quantum dots (claimed) e.g. spotlight used in various energy and display application. ADVANTAGE - The method is simple and economical and enables effective manufacture of graphene quantum dots having high quality, uniform size and shape, minimized number of defects, and excellent electronic properties, and little impurities. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of manufacture of the graphene quantum dots.
