The graphene oxide powder was synthesized from Graphite powder by a modification of Hummer’s method. The GO is exposed to focused sunlight to obtain reduced graphene oxide (rGO). The reduction of GO under solar light is an eco-friendly method to conventional method of rGO preparation. The mechanism of the reduction of GO by sunlight imperative to exfoliation was seen to be well defined. The rGO powder was characterized by Xray Diffraction (XRD), Field-Emission Scanning Electron Microscopy (FESEM), Raman spectroscopy, Fourier-Transform Infrared Spectroscopy (FTIR) and High-Resolution Transmission Electron Microscopy (HRTEM). This eco-friendly method of synthesizing of rGO paves way for an alternative method of rGO nanosheets preparation and it can be effectively used for fabrication of various electronic devices.</p></abstract><kwd-group xml:lang="en"><kwd>reduced graphene oxide</kwd><kwd>crystal structure</kwd><kwd>reduction</kwd><kwd>exfoliation</kwd><kwd>raman</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Anand K., Singh O., et al.
