Abstract

The degree of oxygen-functional groups in graphene-based quantum dots (QDs) is controlled by chemical oxidation and reduction processes. On page 3773, T. S. Seo, Y.-H. Cho, and co-workers exhibit the luminescence mechanisms of a series of graphene-based QDs and observe an irreversible photoluminescence emission between those changing from pristine to oxidized graphene QDs via oxidation processes and those from oxidized to reduced graphene QDs via reduction processes. This is attributed to the different formation of atomic structures by the chain of the chemical oxidation and reduction processes.
