Novel Method of Evaluating the Purity of Multiwall Carbon Nanotubes Using Raman Spectroscopy
Figure 3
(a) Raman spectra, taken using an excitation wavelength of 633 nm, of purity-controlled MWCNT samples with purities ranging from 0% to 100% with 20% interval. (b) Purity measured from Raman spectroscopy using 633 nm laser versus constructed content of MWCNTs.
