CsxWO3 film is a popular near-infrared shielding material that is prepared on the surface of glass by dispersing the CsxWO3 powder into polyvinyl alcohol (PVA) solution. Wherein, cesium tungsten bronze (CsxWO3) powder was synthesized by hydrothermal method. The raw materials are sodium tungstate dihydrate and cesium carbonate, and the organic inducer is citric acid.

Cesium tungsten bronze, with the formula of CsxWO3, is a very important functional material for preparing transparent conductive thin film as cesium tungsten bronze nano particles possess more excellent visible light transmittance, electronic conductivity and UV/IR shielding ability than tungsten trioxide and even commercial ITO glass materials. Therefore, CsxWO3 also has extremely high-potential applications in smart window materials and biomedical materials.

Cesium tungsten bronze particles are applied for preparing heat insulation coating as they have good shielding performance to near-infrared rays and high transmittance to visible light. In other words, heat insulation coating of cesium tungsten bronze particles shields heat radiation in the sunlight without influencing the day lighting. Also, cesium tungsten bronze nanoparticles have significant catalytic property.

Cesium tungsten bronze, or CsxWO3, is known as a near infrared absorbing material because it can selectively absorb near-infrared light, through local surface plasmon resonance and polaron resonance. Well, how to prepare cesium tungsten bronze?

Hexagonal cesium tungsten bronze, as a near infrared shielding material, is more and more widely used to prepare heat insulation film or thermal insulation coating for applying to glasses of buildings and automobiles. According to the experts, the mechanism of low-energy optical absorptions in cesium tungsten bronze is still a matter of controversy, although plasmon and polaron mechanisms have been proposed as a dominant cause. So, they studied hexagonal cesium tungsten bronze nanoparticles to find the systematic analysis results on structural and optical changes with varied amount of oxygen vacancy (VO) and alkali content.

Cesium-doped tungsten bronze, or cesium tungsten bronze, is well-known as a near infrared shielding material, which can selectively absorb near-infrared light by localized surface plasmon resonance and polaron resonance. So, it is often used in the preparation of heat insulation coatings, heat insulation films and other heat insulation products. And therefore, it has broad application prospects in buildings and automobiles. Well, how to prepare cesium-doped tungsten bronze for near infrared shielding material?

Tungsten oxide film, as an important functional material, is often used to produce an inorganic all solid-state electrochromic device. According to the experts, the excellent reversibility of such a device is associated to the presence of an optical free-carriers tail.

WO3 film is well-known as it is the most important electrochromic layer material for assembling an all-solid-state electrochromic device. According to the experts, an all-solid-state electrochromic device based on NiO/WO3 complementary structure and solid polyelectrolyte can be manufactured for modulating the optical transmittance.

WO3 film is often used as an electrochromic layer for the assembly of an all solid-state electrochromic device with the advantages of good durability, high transmittance modulation, high coloration efficiency and good response times. And such a device is more and more widely applied to the curtain wall for adjusting the solar heat radiation dynamically and saving energy.

WO3 film is the most popular material for assembly of an inorganic all solid-state electrochromic device with the characteristics of low power consumption (<2 V), high coloration efficiency and memory effects. So, such an electrochromic device has many potential applications in smart windows, mirrors, displays, and optical switching devices. Wherein, WO3 smart windows is regarded as an energy-saving window with a wide application in buildings and high-class automobiles.
