Cesium tungsten bronze powder with excellent optical performance are mainly applied for obtaining coating glass – an energy-saving glass, which can shield heat and ultraviolet. Wherein, the raw material is cesium tungsten bronze nanocrystals. You know, the controllable synthesis of nanocrystals with a desired structure and morphology is still a great challenge in the chemistry and materials fields.

Cesium tungsten bronze for green building glass curtain wall can be prepared via flame-assisted spray pyrolysis. It is reported that some experts have synthesized the highly crystalline and hexagonal single-phase cesium tungsten bronze (Cs0.32WO3) nanoparticles by a flame-assisted spray pyrolysis followed by annealing under a reducing gas atmosphere.

Cesium tungsten bronze can be prepared into highly transparent heat insulation coating for applying to the smart window glass, thereby reducing room temperature and saving energy. Wherein, the cesium tungsten bronze can be prepared via hydrothermal method. For example, the experts synthesized single-crystalline cesium tungsten bronze (CsxWO3) nanorods with typical diameters of 10–200 nm and lengths of several micrometers via hydrothermal synthesis.

Cesium tungsten bronze for near infrared shielding material can be prepared via a simple thermal decomposition process involving the combination of ammonium metatungstate with oleylamine as both the surfactant and the solvent.
