摘要

A quantitative purity evaluation of single-wall carbon nanotubes (SWCNTs) using resonance Raman spectroscopy was proposed. Linearity between purity and G-band Raman intensity of isolated SWCNT solution was confirmed and quantitative purity was evaluated directly from an intensity ratio of pristine and high-purity SWCNTs prepared by ultracentrifugation. We confirmed that the purity evaluated by Raman intensity of pristine and ultracentrifuged topping of SWCNTs [purity evaluated by Raman intensity of pristine and ultracentrifuged topping of single-wall carbon nanotubes (PERIPUTOS)] gave the same value for the different laser wavelengths and could be applied to any kinds of SWCNT.
