SWNT (Single-walled carbon nanotubes) were synthesized by a laser vaporized CCVD (Catalytic Chemical Vapor Deposition) technique. The diameter distribution and the abundance of SWNT synthesized at different temperatures, and catalysts were investigated by Raman spectroscopy. With increasing synthesis temperature, the diameter distribution shifted towards larger diameter and the G/D ratio became larger as the synthesis temperature increased to 1000℃. Ni, Co and Fe played a catalytic role, though Fe was less effective at our experimental conditions. The diameter distribution of SWNT synthesized with the Fe catalyst was shifted to the smaller diameters in comparison with those synthesized with Ni or, Co catalyst.
