英文摘要We explore the possibility of using metal nano-particles to enhance the Raman scattering of single walled carbon nanotubes (SWCNTs) at high temperatures, with the aim of obtaining enhanced in situ Raman spectra of SWCNT during chemical vapor deposition (CVD). Particle position, metal type, film thickness, excitation wavelength are systematically optimized to meet the requirements for high temperature and in situ measurements. Au particles provide a weak but stable enhancement up to 1000 °C, while the enhancement factors of Ag particles decrease at elevated temperatures due to morphology change and metal evaporation. After the morphology relating effects are eliminated, surface enhanced Raman scattering (SERS) of SWCNT is confirmed to be almost temperature independent in our SWCNT-Ag/Au system. Finally, in situ enhanced spectra with identifiable RBM peaks are obtained in a realistic CVD growth of SWCNTs. The mechanism behind the relatively low enhancement factor is also discussed.
