The electrochromic property of wo3 thin film preparing by magnetron sputtering under various crystal structures

الملخص EN

Tungsten Trioxide (WO3) thin films with a various crystal structure have been fabricated by a magnetron sputtering method.

The effect of changing of crystal structure on the Electrochromic (EC) property was investigated.

Atomic force microscopy (AFM) and X-ray diffraction (XRD) have been employed to investigate morphology and structure.

For EC measurement, 0.1M LiClO4 aqueous solution was used as electrolyte, and Pt and Ag/AgCl were used for counter and reference electrodes respectively.

WO3 thin film with a various structure has been obtained by changing reactive gas (Ar) gas and O2 flow rates.

Fabricated WO3 thin films with 002 and 112 crystal structures have a high Electrochromic (EC) response.
