Investigated raman spectroscopy of graphene material properties
Raman spectrum of a graphene edge, showing the main raman features, the D band(˜1350 cm-1), G band(˜1580 cm-1) and 2D band (˜2700 cm-1) taken with a laser excitation energy of 2.41 eV. D band is not easy to be found in the good structure of the graphite, generally D band and G band integral intensity ratio ID / IG, to determine whether the carbon material defects and the crystallization of the pros and cons, but D band is usually also the incident light wavelength with the impact of the incident area. The insert voltage conditions with H2SO4 and KOH is demo in the study. The D band and G band integral intensity ratio ID/ IG is equal 1.08, and FWHM(cm-1) is equal 97.6 value.
