Electrochromic composites films composed of MoO3 doped by tungsten atoms with remarkable response speed and color rendering efficiency via electrochemical deposition

Boosting the electrochromic performance of P-doped WO3 films via electrodeposition for smart window applications

“…21 Gao et al fabricated electrochromic tungsten-doped molybdenum oxide composite films, and an effective W–O–Mo bonding connection appears to be facilitated by the incorporation of tungsten atoms, which made the films show superior performance. 22 However, the films that contain crystalline/amorphous phases often require complicated preparation procedures, the structure should be precisely control to obtain good electrochromic properties. Elemental doping is a more effective choice for electrochemical deposition, many elements have been used for doping during the process of electrochemical deposition, whereas the elements are noble metal elements, which makes their higher cost and poorly reproducible, there is urgent demand to find low-cost elements doping with good reproducible and electrochromic performance.…”

“…Therefore, many approaches have been developed to improve the electrochromic performance of lms by electrochemical deposition, and the use of elemental doping and the combination of crystalline and amorphous phases have been proven to be effective. [17][18][19][20][21][22] By using a simple method of pulsed-voltage electrodeposition, Quy et al synthesized amorphous-crystalline dual-phase WO 3 lms, which signicantly improved the electrochromic performance. 17 A novel electrodeposition-assisted sol-gel method was used by Zhang et al to prepare amorphous/crystalline WO 3 dual-phase laminated lms.…”
