▎ 摘　　要

Bulk synthesis of few-layer graphene (FLG) for industrial applications still remains a challenge for researchers. Here, we report a very simple technique for bulk synthesis of FLG by femtosecond laser ablation of graphite powder suspended in ethanol without the requirement of a controlled environment. Graphite powder, with an average particle size <20m, was suspended uniformly in ethanol and ablated at room temperature using fs pulses (wavelength 800nm and an input beam diameter 8mm) followed by ultrasonication to obtain FLG with a lateral size of 1m. Raman spectroscopy and high-resolution transmission electron microscopy data confirmed the nature and morphology of the FLG. The quality and number of layers in the FLG could be controlled by tuning the laser parameters.
