Low-Cost Preparation of Graphene Quantum Dots by Liquid-Phase Exfoliation of Carbon Fibers

Article Preview

Abstract:

Graphene quantum dots, a kind of advanced carbon material, have become the frontier of condensed matter physics and material science. Here, we develop a plain and cheap preparation of graphene quantum dots by liquid-phase exfoliation of carbon fibers, which were prepared from absorbent cotton through an annealing process at 1000°C. The structure, micro morphology, chemical bond and optical properties of the as-prepared graphene quantum dots were characterized. Results show that the as-prepared graphene quantum dots present a green luminescence and have a narrow size distribution of 3-10 nm.
