Optically Tunable Amino-Functionalized Graphene Quantum Dots

Amino‐functionalized graphene quantum dots (af‐GQDs) with discrete molecular weights and specific edges were self‐limitedly extracted from oxidized graphene sheet. Their optical properties can be precisely controlled only by the selective and quantitative functionalization at the edge sites. The af‐...

Summary:Amino‐functionalized graphene quantum dots (af‐GQDs) with discrete molecular weights and specific edges were self‐limitedly extracted from oxidized graphene sheet. Their optical properties can be precisely controlled only by the selective and quantitative functionalization at the edge sites. The af‐GQDS exhibit bright colorful fluorescence under a single‐wavelength excitation.
