Reference Information about Tungsten Oxide Powder

Tungsten trioxide is used for many purposes in everyday life. It is frequently used in industry to manufacture tungstates for x-ray screen phosphors, for fireproofing fabrics and in gas sensors.Due to its rich yellow color, WO3 is also used as a pigment in ceramics and paints. In recent years, tungsten trioxide has been employed in the production of electrochromic windows, or smart windows. These windows are electrically switchable glass that change light transmission properties with an applied voltage.This allows the user to tint their windows, changing the amount of heat or light passing through. Recently, some research groups have demonstrated that non-metal surface such as transition metal oxides (WO3, TiO2, Cu2O, MoO3, and ZnO etc.) could serve as a potential candidate for surface-enhanced Raman spectroscopy substrates and their performance could be comparable or even higher than those of commonly used noble-metal elements. There are two basic mechanisms for this application. One is that the Raman signal enhancement was tuned by charge transfer between the dye molecules and the substrate WO3 materials. The other is to use the electrical tuning of the defect density in the WO3 materials by the oxide leakage current control in order to modulate the enhancement factor of the SERS effect.
