Abstract

A systematic investigation of the synthesis of homogenous Cs xWO3 nanorods by a designed water-controlled release process was carried out. The results revealed that the uniform rod-like Cs xWO3 nanoparticles with a Cs/W atomic ratio of ca. 0.33 can be obtained by using 20 vol% CH3COOH-80 vol% CH 3CH2OH mixed solution as a reaction solvent at 240°C for 20 h. The morphology of products were changed depending on the speed of water-releasing process, meanwhile, the Cs/W atomic ratio could be controlled by both the amount of released water and the reaction temperature. Cs xWO3 nanorods showed a high transmittance in the visible light region and excellent shielding ability of near infrared (NIR) lights, indicating that CsxWO3 nanorods have a suitable characteristic as solar filter applications.
