Laser Beam-Induced Transient Acoustic Waves in Graphene Oxides

Abstract

Physica Status Solidi A published by Wiley-VCH GmbH 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.
