Effect of Reaction Temperature on Structural and optical Properties of Reduced Graphene Oxide

Prerna Bansal, A. S. Panwar, and D. Bahadur
Abstract—Present study is aimed to see the influence of reaction temperature on the structural and optical properties of reduced graphene oxide powder samples. In the present work, aqueous solutions of graphite oxide (GO) were reduced at two different temperatures (80 and 95°C) using hydrazine hydrate. XRD and Raman studies showed that sample reduced at higher temperature has lesser defects. UV-visible spectral studies showed a blue shift in the absorption peak of GO after reduction due to the increased structural ordering because of restoration of sp2 carbon with temperature. More shift is observed for the sample reduced at higher temperature. In our work reaction temperature had a great impact on crystallinity and optical properties of our samples. Our study establishes a correlation between structural and optical properties of reduced graphene oxide powder samples with temperature.

Index Terms—Graphite oxide (GO), reduced graphene oxide (RGO), photoluminescence (PL).
