Near-infrared Shielding Material: CsxWO3

As a new type of near-infrared shielding material, CsxWO3 (cesium tungsten oxide) has selective and strong near-infrared absorption in the range of 800 to 1200 nm. And it is reported that cesium tungsten oxide diminishes near-infrared rays of shorter wavelength which has much of the heat energy in sunlight compared to ITO (tin-doped indium oxide) and ATO (antimony-doped tin oxide).

Therefore, cesium tungsten oxide is more and more popular in the preparation of different types of near-infrared shielding materials such as heat insulation films and heat insulation coatings for applying to automotive and architectural windows. When it is applied to the automotive windows, it suppresses temperature rise inside the car. And when it is used as a residential housing material, it improves your comfort. So, cesium tungsten oxide such as Cs0.32WO3 or Cs0.33WO3 is attracting more attention as it has high heat insulation and high infrared shielding performance.
