Cs doped tungsten oxide nanoparticles for producing dingal film may be Cs0.32WO3 nanoparticles with excellent near-infrared shielding ability. However, there are still some critical issues for industrial applications, such as, photochromic instability – a blue color change of Cs doped tungsten oxide nanoparticles under ultraviolet irradiation. But do you know why CsxWO3 nano particles change color? More details, please visit: http://cesium-tungsten-bronze.com/index.html The color changes because of the formation of HxWO3 phase through doping of H+ ions into Cs-deficient sites present…
