摘要：

Fluorinated graphene quantum dots (F-GQDs) were synthesized by cutting fluorinated graphene through a hydrothermal approach. The F-GQDs with oxygen-rich functional groups have a F/C atomic ratio of ca. 23.68% and diameter of 1-7 nm. The photoluminescence (PL) properties of the F-GQDs were investigated. The results showed that besides exhibiting bright blue PL, the F-GQDs display a clear upconversion PL. (C) 2013 American Institute of Physics. [http://dx.doi.org/10.1063/1.4774264]
