Tungsten oxide has visible light responsiveness, that is, it can absorb light energy in the visible light range and trigger corresponding photochemical reactions. Traditional tungsten oxide materials mainly have high absorption capacity for ultraviolet light, but weak absorption for visible light. However, after adjustment and modification, the visible light responsivity of tungsten oxide materials has been significantly improved.
When the tungsten oxide material is irradiated by visible light, the electrons in its energy band structure will be excited to the conduction band or higher energy level excited state. The electrons in these excited states have a long lifetime and can participate in photochemical reactions, such as photocatalysis, photoelectrochemistry, and photovoltaic cells. By adjusting the structure, morphology, crystal phase and surface properties of tungsten oxide materials, its ability to absorb visible light can be enhanced, thereby expanding its visible light response range.
Utilizing the visible light responsiveness of tungsten oxide, a series of applications can be realized, including photocatalytic degradation of organic pollutants, photolysis of water to generate hydrogen, visible light photocells, photoelectrochemical sensors, etc. In addition, the visible light responsiveness of tungsten oxide can also be used in the fields of optoelectronics and optoelectronic devices, such as visible light detectors, photoresistive materials, and visible light responsive optoelectronic devices.
It should be noted that the visible light responsivity of tungsten oxide materials depends on many factors, including the crystal phase structure of the material, lattice doping, surface modification, etc. Therefore, in practical applications, these factors need to be considered in the design, preparation and modification of tungsten oxide materials in order to achieve more efficient visible light response performance.
