Tungsten oxide (WO3) can exhibit a variety of colors, depending on factors such as its crystal structure, morphology, and surface treatment. The following are common colors of tungsten oxide:
Yellow Tungsten Oxide
Tungsten trioxide usually appears yellow, which is its most common color. Yellow tungsten trioxide can be extracted from natural ores or obtained through chemical synthesis.
Blue Tungsten Oxide
Under certain preparation conditions, tungsten oxide can appear blue. This may be related to the change of tungsten oxide crystal structure, the existence of oxygen vacancies or defects.
Violet Tungsten Oxide
Under specific preparation conditions, blue or purple tungsten oxide can be obtained. This color is often associated with impurities or doping, such as the incorporation of specific metal ions or by special precipitation methods.
Purple: Under certain conditions, tungsten oxide can appear purple. This is also related to changes in the crystal structure, oxygen vacancies or defects.
Gray Tungsten Oxide, Black Tungsten Oxide
Reduced tungsten oxide (the reduced form of WO3) can appear gray or black. This form of tungsten oxide is usually prepared under high temperature conditions and has different crystal structure and electronic properties.
Brown Tungsten Oxide, Brown Tungsten Oxide
Tan or brown tungsten oxide is also a possible form. This is usually achieved under specific preparation methods or processing conditions and may be related to changes in the crystal structure or the presence of oxygen vacancies.
Color representation may be affected by viewing conditions and lighting. In addition, the color of tungsten oxide can also be adjusted by adding other elements, surface modification and nanostructure to meet the needs of specific applications.
