Abstract

Helpful elements: A facile bottom‐up method using citric acid and L‐cysteine as a precursor has been developed to prepare graphene quantum dots (GQDs) co‐doped with nitrogen and sulfur. A new type and high density of surface state of GQDs arises, leading to high yields (more than 70 %) and excitation‐independent emission. FLQY=fluorescence quantum yield.
