Raman spectroscopic characterization of some commercially available carbon black materials

摘要: Abstract Some commercially available carbon black materials were characterized by Raman spectroscopy. The spectra recorded between 1000 and 1800 cm−1, which corresponds to the spectral region that provides most valuable data on microstructure of carbons. A comparative study intensity, bandwidth frequency shifts D G bands, as well broad amorphous feature, is presented here. curve fitting method also proposed in order improve accuracy determining spectroscopic parameters main bands. Correlations structure established. samples found correspond low sp2 bonded carbons, but cannot be considered truly since they have some degree basal plane.
