Tungsten oxide film is a thin film layer made of tungsten oxide (WO3) material. Tungsten oxide is a functional material with many applications, and its thin film form is widely used in various fields. Tungsten oxide thin films can be prepared by a variety of methods, including physical vapor deposition (PVD), chemical vapor deposition (CVD) and solution methods.
Tungsten oxide thin films have many features and properties, as follows:
- Optoelectronic properties: Tungsten oxide thin films have tunable optoelectronic properties in the visible and near-infrared spectral ranges, including absorption, transparency, and refractive index.
- Color-changing properties: Tungsten oxide thin films can show reversible color changes through external stimuli (such as temperature, electric field, etc.), and the common change is from colorless to blue.
- Electrochemical activity: Tungsten oxide thin films have good electrochemical activity and have potential applications in electrocatalysis, electrochemical sensing, and electrochromism.
- Thermal stability: Tungsten oxide film has high thermal stability and can maintain stable structure and performance under high temperature environment.
- High transparency: Tungsten oxide film has high transparency in the visible light range and can be used in optical coatings, windows, displays and other applications.
- Gas-sensing properties: Tungsten oxide thin films are sensitive to certain molecules in the gas environment and can be used in gas sensors and detection devices.
Due to its diverse characteristics and wide application potential, tungsten oxide thin films have been widely studied and applied in the fields of optics, electronics, energy, sensors, etc.
