Has excellent optical properties. The following are several characteristics about the light absorption ability of tungsten trioxide:
Tungsten Trioxide Absorbs Visible Light
Tungsten trioxide exhibits a high absorption capacity in the visible light range (approximately 400 nm to 800 nm wavelength). This makes it potentially valuable in optical applications.
Tungsten Trioxide Wide Bandgap
The energy gap of tungsten trioxide is about 2.6 eV to 2.9 eV, corresponding to a wavelength range of about 430 nm to 480 nm. This means it absorbs most of the energy of visible light.
Strong Absorption Peak Of Tungsten Trioxide
In the visible range, tungsten trioxide exhibits a major absorption peak, usually in the blue to violet spectral region. At this peak, its absorption rate is high.
Tungsten Trioxide Photothermal Conversion
Due to its high light absorption capacity, tungsten trioxide has potential uses in light-to-heat conversion applications. It can convert the absorbed light energy into heat energy, which can be used in the fields of solar thermal power generation, photothermal catalysis and photothermal sensor.
The light absorption ability of tungsten trioxide is affected by the material preparation and structure. By adjusting the thickness, crystal structure, doping and other parameters of the film, its optical properties and absorption capacity can be optimized. In summary, tungsten trioxide has strong visible light absorption ability, which makes it potential in optical and optoelectronic applications, especially in the field of light-to-heat conversion.
