Adsorption and Defect-Sensitive Structure of Single Wall Nanocarbons
All the carbon atoms in single-wall nanocarbons, such as single-walled carbon nanotubes (SWCNT) and single-walled carbon nanohorn (SWCNH), are exposed at the surface, making them quite sensitive to the nanoscale environments. Adsorption of alcohol molecules gives a higher frequency shift of the radial breathing mode (RBM) of the Raman spectrum, which corresponds to a compression effect by several GPa. Encapsulation of methylene blue molecules in the internal tube spaces of SWCNT leads to a higher frequency shift of the RBM peaks. The pentagon and heptagon in the carbon hexagon walls bring about the flexible motion in the SWCNT and SWCNH, which can be detected by surface enhanced Raman scattering (SERS).
