Characterization of Chemically Synthesized Ag_2Se Nanowires via Anodic Alumina Membrane as Template

摘要

Highly ordered nano crystallized Ag_2Se nanowires of diameter 200 nm have been successfully prepared through direct chemical method using Anodic Alumina Membrane (AAM) as a template; AgNO_3 as cation precursor agent and Na_2SeSO_3 as Se precursor, respectively at room temperature. The qualitative analysis of the EDAX spectrum of nanowires shows that the atomic composition of Ag and Se in synthesized nanowires is close to 2:1 stoichiometry. XRD spectrum confirms orthorhombic structure. UV-Vis absorption spectrum provides estimation of the optical band gap 1.41 eV of nanowires.
