Cs doped tungsten oxide nanoparticles may be prepared into dispersion at first. And then the dispersion of cesium tungsten bronze nano particles may be prepared into heat insulation coating for spraying on the glass substrate of buildings or autos to obtain energy-saving window. It is believed that such an energy-saving window of Cs doped tungsten oxide nanoparticles is promising in solving the problems of heat insulation and reducing carbon dioxide emission, thereby improving human comfort and protecting the environment.

According to the experts, homogeneous dispersions of tungsten bronze nanoparticles with ternary additives Cs can be prepared in the wet process and examined for optical properties. And the dispersion of cesium tungsten bronze nanoparticles is found to show a remarkable absorption of near infrared light while retaining a high transmittance of visible light. This property is highly suitable for solar control filters in automotive and architectural windows.
