摘要：

The Raman spectra of individual multiwalled carbon nanotubes (MWCNTs) with the innermost diameters of 0.60.9 nm are studied by surface-enhanced Raman scattering. The influences of small innermost diameters to Raman features are investigated. A clear and relatively sharp Raman peak appears at 1510 cm-1 when the innermost diameter is close to 0.6 nm. Lorentzian fits of G band indicate that its splitting is affected by the small innermost diameter of MWCNT. Moreover, the splitting of 2iTO mode is also observed at 28003000 cm-1.
