氟化石墨烯量子点（F-GQD）是通过水热法切割氟化石墨烯合成的。具有富氧官能团的F-GQD的F/C原子比约为1。 23.68%，直径1-7 nm。研究了 F-GQD 的光致发光 (PL) 特性。结果表明，F-GQD 除了表现出亮蓝色 PL 外，还表现出清晰的上转换 PL。 (C) 2013 年美国物理研究所。 [http://dx.doi.org/10.1063/1.4774264]
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]
