Metallic single-walled carbon nanotubes (SWCNTs) have been regarded as unique quasi-1D metallic systems. Their basic properties significantly differ from those of their semiconducting counterparts even though their chemical compositions and sizes are

Quasi-one-dimensional nanotubes and two-dimensional nanoribbons are two fundamental forms of nanostructures, and integrating them into a novel mixed low-dimensional nanomaterial is fascinating and challenging. We have synthesized a stable mixed low-d

Band gap photoluminescence (PL) of single-walled carbon nanotubes (SWCNTs) encapsulating C60 fullerenes (nanopeapods) is examined over a wide range of diameters (∼1.25−1.55 nm). The encapsulated fullerenes induce characteristic PL peak shifts tha

We report optical band gap modifications of single-walled carbon nanotubes upon C60 insertions by using photoluminescence and the corresponding excitation spectroscopy. The shifts in optical transition energies strongly depend on the tube diameter (d

Nitrogen-doped visible light-driven TiO 2 photocatalyst powders were prepared at different temperatures and with different calcination times in a cylindrical tubular furnace under a stream of ammonia gas. Band-gap energy was from 2.92 to 3.04 eV, cor

We observed the chemical adsorption with gas-phase phosgene on TiO 2 surfaces using in situ FT-IR, and examined its effect on the photocatalytic decomposition of trichloroethylene (TCE). The infrared spectrum of the adsorbed standard phosgene suggest

The optical response of single-walled carbon nanotubes (SWCNTs) to far-infrared (FIR) radiation was systematically studied using various SWCNTs with different tube-length distributions. The observed peak position in the FIR spectra linearly scaled wi
