The morphology-controlled synthesis and near-infrared absorption properties of W18O49 were systematically investigated for the application of innovative energy-saving windows. Various morphologies of W18O49, such as nanorods, nanosheres, etc. with various sizes were successfully synthesized by solvothermal reactions using various alcohols as reaction media and, W(EtO)6 and WO3 sol as W source. The W18O49 nanorods of less than 50 nm in length showed the best optical performance as an effective solar filter, which can realize high transmittance in the visible region as well as excellent shielding properties of near infrared light.
