摘要：

Raman spectroscopy study of multi-wall carbon nanotubes (MWNTs) of different diameters (with a small controllable number of walls) produced using Fe-Co catalyst with a variable size of the same active component has been performed. We have characterized as produced MWNTs with different diameters (series 1) and two types of tubes with fixed mean diameters (similar to 10 and 20 nm) heated in a flow of pure argon at various temperatures (2200, 2600, and 2800 degrees C-series 2). The Raman spectra of MWNTs have been registered in three spectral regions, corresponding to D (disorder-induced), G (graphite) and 2D (two-phonon scattering) bands. A ratio of intensities I(2D)/I(D) of tubes of series 1 has demonstrated almost a linear dependence on the nanotube diameters. After heating (series 2), D (disorder-induced) Raman band has shown a substantial decrease in intensity. The variation of the Raman spectra parameters is discussed in terms of defectiveness of nanotubes. (c) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
