▎ 摘　　要

A new strategy for synthesizing highly dispersible, fluorescent graphene-based materials (GBMs) with submicrometric lateral dimensions is presented. GBMs were obtained in a single step through the exfoliation and fragmentation of conventional graphite oxide after underwater shock wave exposure, due to an oxidative cleavage process in the presence of hydrogen peroxide. The obtained materials were characterized using FTIR, Raman, XPS, fluorescence spectroscopy, AFM, TEM, DLS, and zeta potential. The number of shock waves and the concentration of graphite oxide plays a key role in the final properties of GBMs. The fluorescence, size, and chemical structure of shock wave-synthesized GBMs suggest their potential application for energy cells, sensors, bioimaging, and the production of paper-like membranes.
