▎ 摘　　要

F and N co-doped reduced graphene oxide (F,N-RGO) was synthesized by annealing the mixture of N-doped reduced graphene oxide (N-RGO) and XeF2 at 180 degrees C. The photoluminescence (PL) properties of F,N-RGO were studied. The results show that F,N-RGO exhibits two strong ultraviolet (UV) PL centered at 365 and 310 nm, and the PL at 310 nm can be appropriately tuned by tailoring the N content further.
