Nano Cs0.33WO3, or nano cesium tungsten bronze, is a type of near infrared shielding material. The photochromic property of CS0.33WO3 is derived from the fact that the small radius metal ions (Cs+) in the cesium tungsten bronze can enter and exit freely in the tunnel structure. Cesium tungsten bronze is also called Cs-doped tungsten bronze or Cs-doped tungsten oxide. And its doping method is reversible doping. When the doping amount of the metal ions (Cs+) is changed, cesium tungsten bronze…

Nano cesium tungsten bronze is a kind of near infrared shielding material. And the study of the selective transmittance mechanism of cesium tungsten bronze found: In cesium tungsten bronze, the valence state of tungsten is a mixture of hexavalent (W6+) and pentavalent (W5+), and charge carrier hopping between the two valence states are very likely to occur. When W5+ is oxidized to W6+, lattice vacancies will occur, and the electrons lost by tungsten will occupy vacancies and become color center.…

Cesium tungsten bronze is a kind of near infrared shielding material, which can be used for preparing heat-insulating coatings or thermal insulation films. Thus, it can be applied to architectural glass, such as glass curtain wall, glass door and glass window, as well as automotive film and other applications. Optical Properties of Cesium Tungsten Bronze Since cesium tungsten bronze has a special structure of internal tunnel and transport characteristics of carrier, it has many excellent optical properties such as electrochromism,…

Cesium tungsten bronze nano powder is Cs-doped tungsten bronze nano powder, which belongs to tungsten bronze material and near-infrared shielding material. When the cesium tungsten bronze powder is applied to shield near-infrared rays as window film or auto film, it can effectively shield near-infrared rays and ultraviolet rays. Also, this kind of film can guarantee day lighting as it has high transmittance of visible light. Tungsten bronze can form different structures such as cubic structure (CTB), tetragonal structure (TTB), intergrown…

CsxWO3, Cs-doped tungsten bronze, is not only a tungsten bronze material, but also a type of near infrared shielding material. Tungsten bronze materials have attracted widespread attention for their excellent ferroelectric, piezoelectric, pyroelectric, and nonlinear optical properties. CsxWO3 has similar properties to that of tungsten bronze. Tungsten bronze is a series of nonstoichiometric compounds of formula of MxWO3 with special structure. The value of X is generally a value between 0 and 1. The specific value depends on the doping…

Cesium tungsten bronze powder is a near infrared shielding material, which may not only shield near-infrared light and ultraviolet light, but may also have high visible light transmittance. In other words, it “shields” heat in hot summer. And therefore, it reduces cooling fee. The cesium tungsten bronze may be prepared by ultrasonic chemical method, which has excellent performances of good dispersion and reproducibility. Moreover, the equipment for preparation process is simple. And the raw materials are relatively cheap and easy…

Nano cesium tungstate powder is a type of near infrared shielding material, which may be prepared by various methods. One of the preparation methods is described below. The cesium tungstate powder prepared by this method has the advantages of small particle size, uniform dispersion, less agglomeration and high purity. Also, it is conducive to industrial production. Preparation of Nano Cesium Tungstate Powder Step one: Dissolve ammonium paratungstate (APT) and cesium sulfate in citric acid solution and ethanol solvent, stir evenly,…

Cesium tungstate, as a near infrared shielding material, can be used for heat insulation in hot summer in the fields of construction glass and automotive glass. There is a method for preparing cesium tungstate, which can solve the problems of poor dispersity, poor heat insulation and low visible light transmittance of products prepared by prior preparation methods. Step one: Weight 1.47g sodium tungstate and 0.97g cesium carbonate, add 3mol/L citric acid solution and methanol reagent, stir evenly, and react at…

Cesium tungsten bronze nanopowder is a type of near infrared shielding material that can shield most of the solar radiation. The solar radiation is mainly ultraviolet (in the wavelength range of 200~380nm) and near-infrared radiation (in the wavelength range of 780~2500nnm). Cesium tungsten bronze (CsxWO3) is a mixture of hexavalent tungsten (W6+) and pentavalent tungsten (W5+). The W5+ makes the CsxWO3 more reducible. In CsxWO3, Cs+ is filled in the void formed by WO3. Therefore, cesium tungsten bronze crystals are…
