A Facile method to Synthesize Small Size and Superior Crystalline Cs0.32WO3 Nanoparticles for Transparent NIR Shielding Coatings

Abstract

A simple one step solvothermal route is developed to fabricate homogenous cesium tungsten bronze (Cs0.32WO3) nanoparticles and environment-friendly aqueous solution is used to prepare transparent NIR shielding coatings. According to the results, the addition of Cs+ ions promoted the formation of Cs2WOCl5 crystals, which inhibited hydrolysis process of WCl6 and limited the formation of hexagonal tunnel. Controlled formation of hexagonal tunnel is favorable for Cs+ ions fully entering the hexagonal vacant tunnels to form the Cs0.32WO3 crystals. By the controllable formation process, the superior crystalline Cs0.32WO3 nanoparticles with primary particle size mainly in 30 – 60 nm were synthesized at low temperature of 200 °C and short time of 4 h without any other additives. Furthermore, the Cs0.32WO3 nanoparticles could be well dispersed in the aqueous solution, and the as-prepared coating exhibits high SETS value (0.72) which is kept constant with the increase of film thickness. Simulated solar irradiation experiment reveals that the as-prepared film cut off over about 91.6% radiation. Compared with the ordinary glass and commercial Cs0.32WO3, the simulated model of the real environment revealed that the as-prepared Cs0.32WO3 film showed superior NIR shielding performance for practical application.
