The demand for electronic devices such as smart phones, touch screens and flat panel televisions has been increased over the past decade. These devices need transparent conductors and the most widely used transparent conductor as electrode in these devices is indium tin oxide (ITO) due to its high transparency and low sheet resistance. However, ITO thin films have some drawbacks. They are expensive, difficult to deposit, poorly compatible with flexible substrates. Hence, better alternatives for transparent conductors are being studied. Recently, metal nanowires have received a lot of attention due to their unique physical, chemical and optical properties. Due to excellent properties of bulk silver, silver nanowires have been widely investigated. Recently, it was proved that silver nanowire networks provide a suitable path for charge transport and transmit incident visible light. In this thesis, silver nanowires were synthesized in a larger scale via modified polyol process. Afterwards, as synthesized silver nanowires in the form of networks were used to fabricate transparent and conducting electrodes. This was followed by the use of silver nanowire network based transparent and conducting electrodes were used as anodes in organic light emitting diodes (OLEDs). Finally, ambient stability of silver nanowire networks and fabrication of NiO / Ag NWs nanocomposite electrodes were investigated
