Cesium-doped tungsten oxide powder is also known as cesium tungsten bronze powder, whose chemical formula is CsxWO3. It is a type of tungsten bronze type (TB).
As you may have known, tungsten bronze is a kind of non-stoichiometric material, which has excellent ferroelectric, piezoelectric, pyroelectric and nonlinear optical properties, so it has gradually attracted people's attention. CsxWO3 can be widely used in display devices, or as energy-saving materials, and gas-sensitive materials, etc. Due to the change of valence states of cesium ions and e-, the electrochromism, gasochromic property and photochromism are emerged. And as an energy-saving material, cesium tungsten bronze nanoparticles can be applied to architectural glass.

For the major class of cesium tungsten bronze powder - tungsten bronze, experts have introduced that M in MxWO3 type tungsten bronze is usually one or two elements of alkali metal, transition metal or rare earth elements. And its structure is usually divided into PTB, TTB, ITB, and HTB. MxWO3 type tungsten bronze has a variety of properties due to the variety of structures and the different types and concentrations of M ions.
