Graphene coatings and quantum dots
A single sheet of sp2-hybridized carbon atoms, called graphene, is presently the most widely studied material in the scientific community. Following a brief introduction of graphene and its unique properties, I will present methods for preparing graphene, doped-graphene, and graphene quantum dots. In carbon science, spectroscopy has played a significant role in unraveling several fundamental properties of nanostructured carbons like fullerenes and carbon nanotubes. Drawing from such spectroscopic studies, the effective role of Raman and photoluminescence spectroscopy in elucidating the vibration and electronic properties of graphene and graphene quantum dots will be discussed. Finally, stong evidence for the potential use of graphene coatings in biomedical implants, optical diodes and sensing will be presented.
