Cesium-doped tungsten bronze nanoparticles CsxWO3 (CWO) is a material that achieves both visible light transmission and near-infrared absorption, and is applied to near-infrared shielding materials such as window glass for buildings and automobiles. However, they tend to bleach in hot and humid environments. Suppressing the environmental degradation of CWO and stabilizing its optical properties are very important issues both academically and industrially.
However, since the degradation behavior of CWO is not yet fully understood, a detailed investigation is necessary. Therefore, we investigated microscopically the decoloring degradation behavior of CWO, and tried to elucidate the degradation reaction mechanism by first-principles molecular dynamics calculations.
