CsxWO3, Cs-doped tungsten bronze, is not only a tungsten bronze material, but also a type of near infrared shielding material. Tungsten bronze materials have attracted widespread attention for their excellent ferroelectric, piezoelectric, pyroelectric, and nonlinear optical properties. CsxWO3 has similar properties to that of tungsten bronze.
Tungsten bronze is a series of nonstoichiometric compounds of formula of MxWO3 with special structure. The value of X is generally a value between 0 and 1. The specific value depends on the doping amount of intermittent positive ion. When M ions in MxWO3 (0<x<1) are cesium ions (Cs+), it is cerium-doped tungsten bronze (CsxWO3).
The M ions in MxWO3 may also be monovalent ammonium ions (NH4+), hydrogen ions (H+), and alkali metal ions, etc. And it may also be divalent copper ions (Cu2+) cerium ions (Sr2-), calcium ions (Ca2+), barium ions (Ba2+) and other metal ions. Besides, it may also be rare earth metal elements.
