Tungsten bronze, such as cesium tungsten bronze, may be used to produce transparent heat insulation material. Some experts found that the transparent thermal insulation coating of cesium tungsten bronze nanoparticles can be formed on the glass surface to reduce the indoor temperature by 3-10 °C under the premise of ensuring sufficient lighting and visual permeability. Therefore, the air conditioning energy consumption can be significantly reduced and human comfort can be improved.

Molybdenum doped tungsten bronze can be ammonium tungsten bronze nanocrystals doped with molybdenum. Compared with tungsten bronze, the near infrared shielding performance of molybdenum doped tungsten bronze has been improved. So, do you know why molybdenum doping can improve the near-infrared shielding performance of tungsten bronze?

The tungsten bronze composite material for producing an energy-saving window may be a composite material of tungsten bronze and PNIPAM hydrogel. It is reported that the tungsten bronze and PNIPAM hydrogel can be used to produce an energy-saving window by using the photothermal conversion characteristics of tungsten bronze and the heat-sensitive effect of PNIPAM hydrogel. Well, how does the energy-saving window play a role of transparent heat insulation?

As a new infrared absorbing material, or a spectral selective material, cesium tungsten bronze has received much attention. The spectral selective material may be an infrared absorbing material. And spectral selective materials are not limited to cesium tungsten bronze. It is reported that currently, the spectral selective materials applied for producing energy-saving glasses are mainly Low-E thin films, ITO, ATO, and LaB6.
