Synthesizing fluorinated graphene quantum dots (FGQDs) has been a great challenge due to the chemically inert C-F bond, and few attempts have been made to prepare this material. In this article, a novel, mild and effective method to controllably prepare FGQDs with tunable fluorine coverage and size by employing commercial fluorinated graphite is developed. This method avoids the complex procedures of preparing fluorinated graphene and use of toxic gases, and can be realized under mild conditions. Moreover, the obtained FGQDs possess relatively uniform size, enjoy good solubility and stability in water and exhibit highly bright blue luminescence. (C) 2014 Elsevier B.V. All rights reserved.
