Abstract:   (1014 Views)

In this work, the effect of ethanol and acetone liquid medium on the optical characteristic of graphene oxide produced by laser ablation process was investigated experimentally. The second harmonic beam of a Q-switched Nd:YAG laser of 532 nm wavelength was employed to irradiate the graphite target in ethanol and acetone. The aim of this experimental study was to investigate the liquid medium potential to produce graphene. Produced samples were studied using their UV-Vis-NIR absorption spectrum, TEM images, Raman scattering spectrum and Photoluminescence spectrum. Results confirm that the generated nanostructures are classified into two categories: carbon nanoparticles and graphene nanosheets, although a large part of them have been oxidized. Produced carbon nanoparticles in acetone are larger than nanoparticles in ethanol. Also, the formation of sp2 bonds in the ethanol medium is greater than the acetonee medium.
