Tungsten oxide (WO3) has good light absorption ability in the range of visible light and ultraviolet light. It is a wide bandgap semiconductor material with high transmittance and low reflectivity.
In the visible light range, tungsten oxide exhibits high absorption capacity, especially in the blue and violet light regions. This makes tungsten oxide commonly used in optical applications such as optical filters, optical coatings and optics.
In addition, tungsten oxide also has the ability to absorb in the ultraviolet range. It can absorb short-wavelength ultraviolet light, which makes it widely used in the fields of ultraviolet spectroscopy, ultraviolet photocatalysis and optoelectronics.
It should be noted that the specific light absorption ability depends on factors such as the morphology, crystal structure, thickness and spectral range of tungsten oxide. These factors can affect the degree of light absorption and wavelength selectivity of tungsten oxide.
In summary, tungsten oxide has high light absorption in the visible and ultraviolet ranges and is suitable for applications in optics and optoelectronics.
