Nano tungsten trioxide (WO3) absorbs light mainly in the ultraviolet and visible spectral ranges. The specific absorption range depends on factors such as the crystal structure, morphology and particle size of nano-tungsten trioxide.
The light absorption range of nano-tungsten trioxide usually extends from ultraviolet light (UV) to visible light (Visible), specifically covering the wavelength range from 200 nanometers to 700 nanometers. In the ultraviolet region, the absorption of nano-tungsten trioxide is strong, while in the visible region, the absorption intensity gradually weakens. This absorption property makes nano-tungsten trioxide potentially advantageous in applications such as photocatalysis, photosensitive materials, and electrochromism.
It should be noted that the light absorption properties of nano-tungsten trioxide are also affected by factors such as the size, shape and distribution of nanoparticles. In addition, through methods such as doping or surface modification, the absorption range and absorption intensity of nano-tungsten trioxide can also be adjusted to meet the needs of specific applications. Therefore, in specific research or application, optical testing and analysis can be performed on the nano-tungsten trioxide sample used to obtain more accurate absorption range information.
