One-dimensional silicon carbide-carbon nanotube composite nanostructure was fabricated using a direct solid reaction process between pure silicon powders and carbon nanotubes at 1 400 ℃ in this paper. A structural and optical analysis
by mean of X-ray diffraction
scanning electron microscopy
Raman scattering and cathodoluminescence spectroscopy were performed. The outer diameter of the as-prepared one-dimensional composite nanostructure was approximately 60 nm. The composite products showed pronounced luminescent properties with three emission bands centered at 2.89
2.39 and 2.22 eV by room temperature cathodoluminescence.
