“…For electrochemical electrochromic materials, the flow of electrical current is only necessary for the change of optical properties. And usually, the additional current is not required to maintain the achieved state [2]. The electrochromic device is composed of two transparent conductors that are facing each other, and electrochromic material deposited on each of them.…”

“…Laser or plasma surface treatment is used to solve these problems in production processes. It should be noted that the laser surface hardening technology allows treating complex shaped parts with minimal zones of thermal influence in comparison with traditional processes (induction, flame and bulk hardening) [1][2][3]. Currently, laser surface hardening is successfully used to improve the wear resistance of responsible parts [4].…”

“…In general, an electrochromic device consists of 5 layers: a transparent electrode, an ion storage layer, an ion conductor layer (electrolyte), an electrochromic layer (containing WO 3 or another electrochromic material), and another transparent electrode . For these devices, the optical change is brought about through the intercalation of the electrochromic layer by the ion storage layer …”

On the coupled ferroelectric‐electrochromic effect of ε‐WO₃

A reversible electrochromic effect has been observed for the first time in flame spray pyrolysis (FSP) processed ε‐WO3 thin films without the use of an ion storage layer and an electrolytic layer. The dark coloration that appears upon the application of a voltage in films deposited on top of interdigitated gold electrodes is localized to the low voltage (−) electrode arm and it switches to the opposite arm upon a reversal of the polarity. Raman spectroscopy indicated that the coloration was not due to intercalation. It is argued here that the coloration is driven by the asymmetric ferroelectric properties of the ε‐WO3 crystals and that this electrochromic reversibility is intrinsically coupled with the polarization switching of the device.

Charge storage layers are an important component of electrochromic devices, which are expected to exhibit high storage capacity and transparency as well as fast electron transfer rates. However, these layers often rely on the (de)intercalation of ions into the crystal lattice of the material and therefore require optimization to be compatible with non‐intercalating electrolytes. In this report, the post‐modification of mesoporous antimony‐doped tin oxide (ATO) nanoparticle layers with a redox‐active cerium compound is described. In particular, the switching of the Ce3+/Ce4+ couple on the conductive nanoparticle scaffold is demonstrated using tetrabutylammonium perchlorate as a non‐intercalating electrolyte. Remarkably, high storage capacities of up to 27 mC cm−2 and transmittance values of ≈90% are achieved. Variation of the antimony doping concentration revealed that nanoparticle layers doped with 15% Sb exhibit the highest capacity, which can be attributed to increased conductivity in the potential range where the Ce3+ ions are oxidized. Finally, the cerium‐modified ATO films show promising performance as charge storage layers in an electrochromic device with a viologen‐anchored ATO layer as the electrochromic working electrode. Switching times of ≈0.4 s highlight the fast electron transfer capability of the cerium‐decorated ATO layer, even when a non‐intercalating electrolyte is used.
