Cesium tungsten oxide is mainly applied for producing energy efficient glass window. And these windows are popular in modern buildings as they are “smart” to shield heat and pass through the visible light, thereby saving energy and ensuring daylighting.

According to the experts, in an attempt to promote energy saving through the clever control of varying amounts of visible light and solar energy in modern buildings, there has been a surge of interest in the novel design of multidingal glass windows otherwise known as “smart windows”. The experts also introduced that the use of near-infrared shielding materials such as tungsten oxides is widespread in this technology. For the case of hexagonal tungsten oxide (h-WO3)-based systems, the overall efficiency is often hindered by the lack of a systematic and fundamental understanding of the interplay of intrinsic charge transfer between the alkali-metal ions and the host h-WO3.
