Abstract
Single-wall carbon nanotubes (SWNTs) were synthesized by laser vaporized catalytic chemical vapor deposition, which is a combination of laser vaporization and alcohol-CCVD technique. Catalyst particles were prepared by pulsed laser vaporization of a metal rod and ethanol vapor were employed as carbon source. The diameter distributions of the synthesized SWNTs were investigated by Raman spectroscopy. In addition to this technique, the conventional laser oven technique was also studied to synthesize SWNTs. The diameter distribution of SWNTs, which is synthesized by laser oven technique, is in narrower than that synthesized by laser vaporization catalytic CVD.
