    • Surface-enhanced Raman scattering (SERS) spectra of single-walled carbon nanotubes (SWCNTs) on silver films with different nano-particle sizes from 20 to 100 nm deposited on quartz and glass substrates were studied systematically. The characteristic Raman spectral features of SWCNT G-band and D-band were analyzed. The two bands show a similar tendency with the change of nano-particle size of silver on quartz and glass substrates. The position and the intensity of the G-band are less sensitive to the films' silver particle sizes in the studied range, indicating that hexagonal carbon rings are stable and have a weak interaction with silver films. The shape of the D-band depends on the silver size. The smaller the silver particle size, the more the contribution of high frequency vibrations to the D-band, indicating that disorder carbon has a strong interaction with the active silver films.

  • SERS study of single-walled carbon nanotubes on silver films deposited on different substrates
  • 2003

  • Tidskriftsartikel (refereegranskat)abstract
    • Surface-enhanced Raman scattering of single-walled carbon nanotubes (SWNTs) on silver films deposited on various substrates, including sapphire, quartz and glass, has been studied systematically. The characteristic features of G-band and D-band have been analyzed and compared with arc discharged and laser ablation samples. D-band is much more sensitive than G-band. The position and the intensity of the G-band in SERS spectra depend on substrates. The peak shift and absolute intensity of G-band on sapphire is obviously larger than that on glass. The contribution of high frequency vibrations to the D-band is also deendent on substrates. Compared to the SWNTs samples with a high semiconducting tube concentration, the sample with high metallic tube concentration has a stronger interaction with silver films.
