In this work, the doping of n-layer graphenes with C60 is investigated via Raman spectroscopy. The results indicate that C60 can induce hole doping in graphenes, and that the doping level is closely related to the layer number of the graphenes. Moreover, the level of doping in the hybrid of C60 on graphene (C60/G) is more significant than that in the hybrid of graphene on C60 (G/C60).
