SeZnSb alloy and its nano tubes, graphene composites properties

Abstract

Composite can alter the individual element physical property, could be useful to define the specific use of the material. Therefore, work demonstrates the synthesis of a new composition Se96-Zn2-Sb2 and its composites with 0.05% multi-walled carbon nano tubes and 0.05% bilayer graphene, in the glassy form. The diffused amorphous structure of the multi walled carbon nano tubes and bilayer gaphene in the Se96-Zn2-Sb2 alloy have been analyzed by using the Raman, X-ray photoluminescence spectroscopy, Furrier transmission infrared spectra, photoluminescence, UV/visible absorption spectroscopic measurements. The diffused prime Raman bands (G and D) have been appeared for the multi walled carbon nano tubes and graphene composites, while the X-ray photoluminescence core energy levels peak shifts have been observed for the composite materials. Subsequently the photoluminescence property at room temperature and a drastic enhancement (upto 80%) in infrared transmission percentage has been obtained for the bilayer graphene composite, along with optical energy band gaps for these materials have been evaluated 1.37, 1.39 and 1.41 eV

“…contributions both the ring and chain; under the most weak effect into the inter-structural forces. 13 In sequence to our systematic study, [14][15][16] this work demonstrates microstructure and a detail description on the UV/Visible optical properties; like absorption spectra, extinction coefficient (k), real dielectric constant ( ), imaginary dielectric constant ( ), refractive index (n), absorption coefficient ( ) and optical energy band, for the Se 96 Zn 2 Sb 2 (SZS) alloy and Se 96 Zn 2 Sb 2 + 0 05% multi walled carbon nano tubes (SZS-MWCNT), Se 96 Zn 2 Sb 2 + 0 05% bilayer Graphene (SZS-GF) composite materials. Along with the mechanism of the composite formation is also discussed.…”
