Abstract
A simple and easy method for fabricating graphene quantum dots with uniformed size and high quality of emission property comprises steps of, mixing graphite powders with metallic hydrate salts, forming an intercalation compound of graphite wherein metal ions are inserted by heating the mixed solution, and removing the metal ions from the intercalation compound of graphite. The graphene quantum dots is applicable to the development of electronic products in next generation such as display devices, recording devices, various sensors and nanocomputers and is applicable to biological and medicinal field as well.
