| Research Abstract |
High-crystalline single-walled carbon nanotubes were mass-produced using arc plasma evaporation of carbon electrodes including Ni and Y catalysts. Optical emission intensities corresponding to C2, Ni and Y species in the arc plasma were measured as a function of arc current. The behaviors of particles yielded by evaporation of carbon electrode were also investigated using Mie scattering spectroscopy. Crystallinity of synthesized carbon nanotubes was evaluation using Raman spectroscopy and transmission electron microscopy observation. On the basis of the information obtained using optical emission spectroscopy and Mie scattering spectroscopy combined with the evaluation of products, growth model of high-quality carbon nanotubes using arc plasma evaporation was proposed.
