Multi-walled carbon nanotubes (MWNTs) of various diameters have been analyzed by Raman spectroscopy to clarify the influence of the diameter of MWNTs on their Raman spectra. The G-band frequency of MWNTs determined by curve fitting decreases with increasing tube diameter for diameters less than around 20 nm, beyond which it is almost constant. We believe that the G-band frequency of MWNTs with diameters less than 20 nm is affected by the interlayer spacing of MWNTs, and the behavior of the G-band frequency of MWNTs with diameters exceeding 20 nm can be explained on the basis of the optical penetration depth in graphite.
