▎ 摘　　要

NOVELTY - Producing graphene quantum dots comprises obtaining a micelle solution, where micelles including water, a carbon precursor, and a surfactant are dispersed in a non-polar solvent and heating the micelle solution to obtain a graphene core. The micelle further including a catalyst i.e. copper nitrate hydrate and aluminum nitrate hydrate dissolved in the water. USE - The graphene quantum dots is useful in nanoelectronics, optoelectronics, and chemical sensors. ADVANTAGE - The graphene quantum dots: has improved optical properties, light emitting characteristics and antibacterial properties, core containing a large amount of graphene; can receive light in a low wavelength range i.e. ultraviolet light and efficiently generate light, generate a large amount of electrons from the core and can be easily transferred to the outside through the ligand; and easily generates active oxygen due to the transferred electrons. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for metal-containing graphene quantum dots comprising a core (110) containing graphene and further including a ligand (120) surrounding the core, which has an average particle diameter of 1-100 nm and the raman shift measured by raman spectroscopy is a first peak at 1300-1400 cm-1 and a second peak at 2600-2750 cm-1. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene quantum dot. 110Core 120Ligand
