One pot rapid synthesis of silver nanowires using NaCl assisted glycerol mediated polyol process

Abstract

We report, one pot rapid synthesis of silver nanostructures from AgNO3 through glycerol mediated polyol process with the assistance of polyvinyl pyrrolidone (PVP) and NaCl. The growth of silver nanostructures was studied by monitoring changes in the position of localized surface plasmon resonance band using the UV-vis-NIR spectroscopy. Morphology of the silver nanostructures was indentified using the scanning electron microscope which confirms the formation of nanoparticle, V-shaped and linear silver nanowires. The favorable temperature and NaCl concentration to obtain nanoparticles, V-shaped and linear silver nanowires are optimized. 5 mM NaCl at 250°C produced 55 — 65 nm width, 4 μm long silver nanowires along [100] in PVP added glycerol medium within 25 minutes.
