Tungsten oxide is a widely used electrochromic material with important applications in variable-transmittance smart windows as well other optoelectronic devices. Here we report on electrochemical impedance spectroscopy applied to hydrous tungsten films wide range of potentials. The were able reversibly bleach and color upon cycling. Interestingly, the bleaching potential was found be significan...

Helium (He)-induced nanostructured tungsten sheets were synthesized by He plasma irradiation under different exposure durations. After calcination, oxide samples used as photoelectrodes to test photoelectrochemical (PEC) performance. The results showed that WO3 photoanodes have higher PEC performance compared the sample without nanostructures. 15 min irradiated had highest photocurrent density ...
