Cesium tungsten bronze may be applied for producing thermal insulation masterbatch — a kind of dingal masterbatch, which has the performance of shielding ultraviolet and near-infrared rays. It is also a kind of tungsten bronze material with excellent optical properties. When tungsten bronze is not doped with Cs+, the tungsten bronze is yellow in color. And when the amount of Cs+ is increased to a certain extent, the color of the cesium tungsten bronze will be changed into blue. It…
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.
