Abstract

In this study, silver nanowires (Ag NWs) were synthesized in a one-pot method from silver nitrate and poly(vinyl pyrrolidone) (PVP), and reduced by ethylene glycol without the presence of chloride ion. The addition of silver nitrate and PVP was controlled by syringes. The syringe rate, and the concentrations of silver nitrate, and PVP, were manipulated to obtain Ag NWs with different widths and lengths. We have observed the phenomena of coarsening and combination of silver nanorods during the growth of the Ag NWs. With these phenomena, we have developed a growth model of Ag NWs, and successfully synthesized Ag NWs with high aspect ratios via the developed model.
