Blue Tungsten Oxide in Electronics

W20O58 nanowire array SEM

Blue tungsten oxide using in electronic industry is mainly depending on special properties of tungsten itself, such as the highest melting point, high hardness, stable chemical property, in addition, some columns of tungsten oxide, tungstate, tungstic acid and other organic or inorganic compounds have special performance, therefore, a series of electronic optical materials, special alloys, new functional materials and organic metal compounds and so on all need to use the unique properties of tungsten.

Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.

The emergence of flexible electronics has made people aware of the future electronic products have a significant breakthrough in the field of human-computer interaction, such as nowadays the more and more popular wearable electronic products, flexible energy storage devices and flexible sensor, flexible building wall advertising, outdoor large screen display, electronic paper and flexible mobile phone screen, etc., and all of these are based on LED or LCD display.

A study has used hot steaming process to prepare blue tungsten oxide (W20O58) nanowires array/carbon fiber structure on carbon cloth fiber, a kind of flexible field emission display (FED), with the properties of flexible cold cathode material, such as high current density and stability, and show the excellent field electron emission performance.
