Cesium tungsten bronze dispersion has high transmittance in the visible light region as well as excellent shielding properties of near infrared light so that it is usually applied for producing heat insulation coating. To improve heat shielding performance of the dispersion, some experts prepared cesium tungsten bronze by surface coating method (PVP-CsxWO3) and template method (CTAB-CsxWO3), and investigated the effects of these two methods on the photothermal properties and photothermal conversion efficiency of cesium tungsten bronze.

W18O49 nanorod, or violet tungsten oxide, may show strong absorption of NIR light and high transmittance in the visible region so that it is often applied to prepare heat insulation coating. And such coating is promising in building energy efficiency. Well, do you know how to synthesize W18O49 nanorod? Some experts have prepared W18O49 nanorod via ammonium tungsten oxide and studied its interesting optical properties.

Tungsten bronze is a selective light-transmitting material (near-infrared shielding material) with the formula of CsWO3, which is often used to prepare transparent heat insulation coating, so that the resulting coating can achieve high transparency while exert excellent heat radiation shielding performance in the entire infrared light region (780- 2500 nm). And therefore, such a coating is often applied to sunrooms, office, living rooms and many other places.

CsxWO3 for producing new transparent heat insulation coating is cesium tungsten bronze --- an inorganic nanoparticle with special optical properties. But why choose a new transparent heat insulation coating of cesium tungsten bronze instead of other heat insulation products?
