Abstract

By microwave-assisted method, silver nanophases were produced with size and morphology control. Silver nanoparticles of controlled size from 10 to 80 nm were obtained. Particle size was controlled by varying reaction conditions, including metal source concentration and molecular weight of protecting agent (PVP). Silver nanowires were produced by releasing the metal source gradually from AgF _n ^1-n(n = 1-6) with PVP as the morphology directing agent. UV-Vis spectra showed that Ag nanoparticles have absorption bands around 400 nm and the UV-Vis absorptions slightly blue shifted with decreasing particle size.
