Research Paper


The present work demonstrated a simple method to synthesize Ag nanowires with a diameter of 60 nm and length of 5–20 μm by reduction of AgNO3 using polyvinylpyrrolidone as not only reducing agent but also capping agent in distilled water assisted with a trace amount of salts. The shape and yield of Ag nanowires significantly depended on the concentrations of these trace salts and reaction temperatures. A mechanism of dynamic dissolution and formation of Ag x A y between anion in salts and freshly formed Ag nucleus has been proposed to explain the growth of Ag nanowires. The Ag nanowires have been applied to form a transparent Ag film with a sheet resistance of 50.2 Ω/sq. and transmittance of 84 % at 550 nm.
