    Abstract

    Csx WO3 nanoparticles in the range of 2050 nm have been successfully synthesized by the supercritical solvothermal approach, where after dissolving WCl6 and CsOH in a mixed solution of water, ethanol and oleic acid, the solution was heated at 300°C. The products were characterized by X-ray diffraction, TEM, HR-TEM, EDS, laser particle size analysis and thermographic measurements. Csx WO3 nanoparticles showed the high transparency in the visible region, excellent shielding performance of the near-infrared light and limited reflectance of light in the range of 2002700 nm, indicating the strong absorption of NIR light on the nanosized Csx WO3. Csx WO3 nanoparticles also exhibited quick conversion of photo-energy to local heat.
