Figure Lengend Snippet: Raman spectra of SWNT samples. ( a ) Raman spectra obtained from purified and bundled Tuball- and arc-SWNTs samples revealing typical Raman signals for SWNTs. Inset in ( a ) shows a zoom-in view of the low-frequency range. ( b ) Zoom-in view of the spectra of ( a ).
Article Snippet: We analyzed two kinds of purified commercial SWNTs, Tuball (Oscial, Russia) and ASA-100F (arc-discharge, Hanwha Chemical, South Korea), where the purity is 80 wt% and 95 wt%, respectively.
