A simple two-step microwave-assisted method was developed for the preparation of adenine-modified graphene quantum dots (A-GQDs) with striking fluorescence properties. The prepared A-GQDs with the lateral size of 3–5 nm and single- to few-layer thickness exhibit intense fluorescence with a quantum y...
