Nano particle size cesium tungsten oxide may be applied for producing thermal insulation film and thus be used to automobile glass to obtain heat insulating window glass. This is because the raw material cesium tungsten bronze nanoparticles have basic characteristics such as macroscopic quantum tunneling effect, quantum size effect, surface effect and small size effect. And it is these properties that make cesium tungsten bronze nanoparticles exhibit many unique physical, chemical, and optical properties.

According to experts, the macroscopic quantum tunneling effect is one of the basic quantum phenomena. If the total energy of the microscopic particles is smaller than the barrier height, the particles can still cross this barrier. Some experts have also explained that the microscopic particles that have the ability to penetrate the potential barrier are referred to as tunneling effect. Also, it has been found that some macroscopic quantities, such as the magnetization of nanoparticles, also have tunneling effect, called macroscopic quantum tunneling effect.
