提出了一种利用共振拉曼光谱定量评价单壁碳纳米管纯度的方法。证实了分离的SWCNT溶液的纯度和G带拉曼强度之间的线性，并直接从通过超离心制备的原始和高纯度SWCNT的强度比评估定量纯度。我们证实，通过SWCNT的原始和超浓缩顶部的拉曼强度评估的纯度[通过单壁碳纳米管（PERIPUTOS）的原始和超浓缩顶部的拉曼强度评估的纯度]对于不同的激光波长给出了相同的值，并且可以应用于任何种类的SWCNT。
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.
