Spontaneous Ag-Nanoparticle Growth at Single-Walled Carbon Nanotube Defect Sites: A Tool for In Situ Generation of SERS Substrate
Figure 2
Raman spectra untreated SWCNT and Ag-treated SWCNT using (a) 2. 41 eV (b) 1.58 eV laser excitation. The laser power measured at the sample was 1 mW for (a) and 0.4 mW for (b). Curve fitting of D and G bands for (c) SWCNT and (d) Ag treated SWCNT.
