Abstract
In this work, a simple and effective method for the synthesis of carbon nanotubes, and graphene-based quantum dots is described. The topological properties of these nanostructures are studied by atomic force and scanning electron microscopes. The potential of quantum dots is investigated by the Kelvin probe method. To study the formed bonds and for a detailed structural analysis, Raman spectroscopy is performed. Other self-organized structures based on graphene are also revealed using Raman spectroscopy. The effect of photon-phonon scattering on the Raman scattering spectrum is also discussed.
