One-dimensional metallic nanostructures, Ag nanowires (Ag NWs), have recently attracted a great deal of attention as electrode material as a promising alternative to ITO for fabrication of electronic devices. In this work, we successfully synthesized Ag NWs whose diameters could be controlled in the range of 20–25 nm and lengths up to 15 μm through the high-pressure polyol method. The nanowire dimensions, especially the diameters, can be controlled by the pressure conditions. At an elevated pressure of 100 psi, the silver could be directly grown into thin nanowires with diameters ranging from 20 to 22 nm. These thin Ag NWs showed an electrical conductivity of 0.4 × 10E5 S/cm, and the intensity of scattered light and the optical transmittance were largely improved. It is clear that such transparent conducting Ag NWs have the potential to outperform conventional ITO thin films, especially when used in flexible OLED devices as a potential electrode layer. |
