Advantages of ultraviolet Raman spectroscopy for study of nanostructured carbon substances

The features of the spectra of weakly ordered graphite-like substances upon excitation of Raman scattering by lasers of different wavelengths (633, 515, and 244 nm) have been analyzed. The advantages of the ultra-violet Raman spectroscopy (244 nm) in comparison to visible (633, 514 nm) have been presented. For the first time spectroscopic characteristics of nanocrystalline graphite, glass-like carbon and shungite, obtained on ultraviolet radiation are described. Features of the method of ultraviolet Raman spectroscopy can be useful for carrying out a phase analysis of multicomponent carbon substances containing sp2- and sp3-carbons.
