The peak intensities of the D-bands and G-bands of the spectra are calculated after baseline removal. Raman spectroscopy has revealed itself to be an invaluable technique for the characterization of ...

The four carbon black samples exhibit typical carbon black Raman signatures that contain G- and D-bands but not 2D-band. The two carbon nanofiber samples exhibit prominent D-bands, demonstrating a ...

Raman spectroscopy can differentiate graphene from graphite or other carbon materials by its unique G-band and 2D-band peaks.
