Notes:
High-quality single-walled carbon nanotubes (SWNTs) are a key aspect in the emergingfield nanotechnology. Although many approaches have been developed, the research on thesynthesis of SWNTs is still needed. In this study, we report the synthesis of high-quality SWNTs byfloating catalyst chemical vapor deposition, which employs ferrocene as the catalyst precursors. Weobtained massive deposits at low temperature region. The deposits were characterized by scanningelectron microscopy, transmission electron microscopy, and visual laser Raman spectroscopy. TheRaman spectrum obtained from raw deposits shows clear radial breathing mode at the range from180cm-1 to 300cm-1 and high-intensity graphite mode at 1577.7cm-1 with a shoulder at 1550.5cm-1,and almost no detectable peak around at 1545cm-1, which is induced by defects, is observed. Theseresults indicate that the deposits are high-quality SWNTs
