Violet tungsten oxide nano powder, like yellow tungsten oxide nano powder or tungsten trioxide nano powder, is an oxide of tungsten, which has optical adjustment properties, so it may be used to produce a smart window. It is reported that a smart window consists of five layers of film on the glass, the structure of which is shown below.

Yellow tungsten oxide is the most commonly used material for the preparation of an inorganic electrochromic film. And the obtained film can be used for producing an all-solid electrochromic glass, that is, the so-called smart glass, which is more and more widely applied in smart buildings to play the role of heat insulation in summer and heat preservation in winter. So, how to prepare WO3 electrochromic film?

Yellow tungsten oxide nanopowder may be used to produce an electrochromic glass, that is, a smart glass with excellent optical adjustment properties. In other words, such smart glass is mainly used to achieve the effects of thermal insulation and heat preservation with high transparency so that it is more and more widely applied in the heat insulating field of construction and automotive glass. for such electrochromic material, experts say that the following reversible reactions occur when the WO3 film is electrochromic:

Yellow tungsten oxide, or tungsten trioxide, may be prepared into an electrochromic film, and then be used to produce a smart glass - a new energy-saving material. Due to its excellent heat insulation and heat preservation performance, such material is more and more widely applied in building energy-saving renovation. Experts say that tungsten trioxide film is probably the most practical electrochromic material in many electrochromic materials.

Yellow tungsten oxide, or tungsten trioxide, has excellent optical adjusting properties and therefore it may be used to produce an all-solid-state electrochromic smart window. According to experts, WO3 electrochromic film is considered to be the most promising inorganic electrochromic material used in construction and automotive windows.

Yellow tungsten oxide nano powder, or nano particle size tungsten trioxide, may be used to prepare a smart window, which is also known as an energy-saving window familiar to the public. Such window has excellent optical adjustment performance, which can achieve the effects of thermal insulation and environmental protection. Also, the smart glass is highly transparent so that it is more and more widely used in glass curtain walls, sunrooms and greenhouses. At the same time, tungsten trioxide is coming to the most people’s sight.

WO3, or tungsten trioxide, has excellent optical properties, so it may be used to prepare an inorganic electrochromic film, that is, a smart film. Such smart film may be applied to glass windows such as buildings, automobiles and airplanes to achieve the performance of heat insulation and heat preservation. According to experts, the optical modulation properties of tungsten trioxide electrochromic films are closely related to their structure.

WO3 nanopowder is an inorganic electrochromic material that exists as a layer of transparent electrochromic film on an electrochromic glass. Since Deb discovered the electrochromic phenomenon of tungsten trioxide film in 1969, extensive research has been carried out on inorganic electrochromic materials and great progress has been made.

Blue tungsten oxide electrochromic film may be used to produce an electrochromic glass, and therefore be applied building glass to obtain a smart window, which is also known as a smart heat insulating glass and a new energy-saving material. As you may have known, requirements for building energy conservation in China are getting higher and higher. Also, the requirements of the energy conservation and intelligence of doors and windows are also getting higher and higher. Nowadays, the types of energy-saving glass used for doors and windows are also increasingly abundant, and electrochromic glass has become a frontier and hot spot for research at home and abroad.

Blue tungsten oxide nano powder has electrochromic properties, so it may be used to prepare a smart window. And the prepared window is suitable for applying to building or automotive window in areas that has a temperate climate or in other places with obvious temperature changes, so tungsten oxide smart glass is the development direction of intelligent buildings.
