Abstract

Laser beam‐induced graphene oxides (GOs) with excellent tunable properties have to find attention in various applications. But, the understanding of the complex mechanics involved in this reduction process is incomplete, most primarily the reduction using ultrashort laser beam pulses. Herein, the influence of laser beam‐induced acoustic waves on the photoreduction as well as the generation of a reversible phase in the GOs using photoacoustic studies is presented. However, these waves influence the phase transition in GOs. These observations find aspiring applications for next‐generation optical technologies, such as data storage and neural chips.

Highlights

Laser beam-induced graphene oxides (GOs) with excellent tunable properties density functional theory and experimental have to find attention in various applications
Laser-induced graphene obtained from graphene oxides (GOs) undergoes a photothermal and photochemical mechanism depending on the irradiation conditions used in the process.[1]
During the laser beam exposures with lower fs laser beam pulse repetition rates such as 10 and 5 kHz in GOs, the presence of ripple waves is observed in charge-coupled device (CCD) camera (Figure 1b)

Summary

Introduction

Laser beam-induced graphene oxides (GOs) with excellent tunable properties density functional theory and experimental have to find attention in various applications. The influence of laser beam-induced acoustic waves on the photoreduction as well as the studies suggest the localized reversible phases in GO material and the wettable GOs with the bond breaking in the material’s atomic structure.[14] Our article explores the generation of laser-induced generation of a reversible phase in the GOs using photoacoustic studies is acoustic waves during GOs’ photoreducpresented. It is reported that during the laser beam irradiation in graphite, a pure form of GOs is influenced by the shock waves, which is a particular case of acoustic waves[10] permanent physical damaging the atomic structure.[11] these studies are insufficient to fully understand the laser beam-assisted reduction process in GOs, especially the photochemical process observed with ultrashort pulses and the ultraviolet regime.[12]
