Thin, transparent, conducting films are critical for many optoelectronic devices and components. They are most heavily used for electrode applications in devices such as liquid crystal, flat panel or plasma displays, touch panels, organic light-emitting diodes (OLEDs), and solar cells but are also commonly used as antistatic coatings and EMI shielding material. Such films are usually made from doped metal oxides, most commonly indium tin oxide (ITO). However, ITO has a number of drawbacks and is unlikely to be the material of choice in future optoelectronic devices. The difficulties with ITO revolve around the rising cost of indium, the brittleness of ITO, and the high temperature processing used in its production. Attempts to resolve the first problem have involved use of alternative metal oxides, thin metal films, or metal grids to prepare transparent conductors. However, the some problems are probably more significant; future displays will be larger and will probably reside on a plastic rather than a glass substrate and so must be flexible. Thus, prospective displays will require flexible transparent electrodes that can be produced at low temperature and over large areas at low cost. So, some research group propose that this problem can be solved by preparing thin films of metallic nanowires. However, there has yet to be any reports on rational methods to control of metal nanowire itself for using transparent electrode. We report on the fabrication of transparent and conductive metal nanowire electrodes through well defined silver nanwires, and new application for colored electrode by using surface functionalized silver nanowire and some dyes.
