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-AgAsS{sub 2} glass composite possess highly increased ionic conductivity, from {sigma}{sub 25} deg. C=4.38+-0.0438x10{sup -6} to {sigma}{sub 25} deg. C=6.57+-0.0657x10{sup -6} S cm{sup -1} and decreased refractive index from n=2.652 to 2.631 at the wavelength {lambda}=1.55 {mu}m. - Graphical abstract: Preparation of multi-walled carbon nanotube-doped chalcogenide glasses by direct synthesis and the melt-quenching method
