Abstract
Graphene nanoballs were produced via cost effective flame synthesis method, and influence of annealing temperature along with annealing time on configuration and quality of the samples were studied. The structural, morphologies, and optical properties of the so formed nanoballs were studied by means of X-ray Diffraction, Scanning Electron Microscopy, Raman Spectroscopy and Energy Dispersive Spectroscopy. The synthesis of graphene was confirmed by both X-ray diffraction and Raman spectroscopy. XRD studies showed the crystalline nature and phase purity of the graphene. Raman studies showed that sample annealed at higher temperature has more defects in comparison to un-annealed sample. Different optical and structural parameters were also performed to further analyze the nanoballs.
