Carbon nanotube-chalcogenide glass composite

This article describes the preparation of multi-walled carbon nanotube-chalcogenide glass composite by direct synthesis and the melt-quenching method. The carbon nanotubes-chalcogenide glass composite was characterized by high-resolution transmission electron microscopy (HRTEM). TEM/energy-dispersive X-ray spectroscopy, low energy electron excited X-ray spectroscopy, Raman spectroscopy, spectroscopic ellipsometry, microhardness, and impedance spectroscopy. CNTs-AgAsS2 glass composite possess highly increased ionic conductivity, from sigma(25 degrees C)=4.38 +/- 0.0438 x 10(-6) to (sigma(25 degrees C)=6.57 +/- 0.0657 x 10(-6) Scm(-1) and decreased refractive index from n=2.652 to 2.631 at the wavelength lambda = 1.55 mu m.
