Single-wall carbon nanotubes with diameters approaching 6 nm obtained by laser vaporization

Single-wall carbon nanotubes (SWNTs) with large diameters from 2 to 5.6 nm were prepared by pulsed laser vaporization of carbon rods doped with Co, Ni and FeS in an atmosphere of Ar:H 2. The SWNT material was characterized by SEM, HRTEM, Raman, IR, UV–VIS–NIR absorption spectroscopy and thermogravim...
