Structure-Assigned Optical Spectra of Single-Walled Carbon Nanotubes
Optical spectroscopy can be used to rapidly determine the detailed composition of bulk SWNT samples, providing distributions in both tube diameter and chiral angle.
Band Gap Fluorescence from Individual Single-Walled Carbon Nanotubes
At pH less than 5, the absorption and emission spectra of individual nanotubes show evidence of band gap–selective protonation of the side walls of the tube, which is readily reversed by treatment with base or ultraviolet light.
C60: Buckminsterfullerene
During experiments aimed at understanding the mechanisms by which long-chain carbon molecules are formed in interstellar space and circumstellar shells1, graphite has been vaporized by laser
Electronic structure of atomically resolved carbon nanotubes
Carbon nanotubes can be thought of as graphitic sheets with a hexagonal lattice that have been wrapped up into a seamless cylinder. Since their discovery in 1991, the peculiar electronic properties
Individually suspended single-walled carbon nanotubes in various surfactants
Individual single-walled carbon nanotubes (SWNTs) have been suspended in aqueous media using various anionic, cationic, nonionic surfactants and polymers. The surfactants are compared with respect to
Gas-phase catalytic growth of single-walled carbon nanotubes from carbon monoxide
Abstract Single-walled carbon nanotubes (SWNTs) have been produced in a gas-phase catalytic process. Catalysts for SWNT growth form in situ by thermal decomposition of iron pentacarbonyl in a heated
Gas-phase production of carbon single-walled nanotubes from carbon monoxide via the HiPco process: A parametric study
We have demonstrated large-scale production (10 g/day) of high-purity carbon single-walled nanotubes (SWNTs) using a gas-phase chemical-vapor-deposition process we call the HiPco process. SWNTs grow
Crystalline Ropes of Metallic Carbon Nanotubes
X-ray diffraction and electron microscopy showed that fullerene single-wall nanotubes (SWNTs) are nearly uniform in diameter and that they self-organize into “ropes,” which consist of 100 to 500 SWNTs in a two-dimensional triangular lattice with a lattice constant of 17 angstroms.
Catalytic growth of single-walled manotubes by laser vaporization
Direct laser vaporization of transition-metal/graphite composite rods produced single-walled carbon nanotubes (SWT) in the condensing vapor in a heated flow tube. A much higher yield of nanotubes was
