Cs Doped Tungsten Oxide Nanoparticles Applied for Window Heat Insulation Film

Cs doped tungsten oxide nanoparticles for producing window heat insulation film are also known as cesium tungsten bronze (CsxWO3) nanoparticles, which are well dispersed with high crystallinity. More importantly, CsxWO3 has excellent near infrared shielding performance and high transmittance to visible light. So, it is believed that cesium tungsten bronze is an attractive candidate for manufacturing energy-saving products such as window heat insulation film for applying to buildings and automobiles.

But why can Cs doped tungsten oxide nanoparticles show excellent near infrared-shielding properties? According to the experts, the reason why cesium tungsten bronze exhibits excellent near infrared-shielding ability is due to the two kinds of absorptions: localized surface plasmon resonance absorption around 900 nm and small polaron absorption near 1800 nm.

In a word, it is localized surface plasmon resonance absorption and small polaron absorption that make CsxWO3 have excellent NIR shielding performance. And it is excellent NIR shielding performance that make CsxWO3 an important material for preparing heat insulation film.
