Cathodic electrodeposition of amorphous tungsten oxide dihydrate film for dual-band electrochromic modulation.

ABSTRACT: Recent advances in hydrated tungsten oxides (WO₃·nH₂O, n = 1, 2) have highlighted their potential for dual-band electrochromic applications. However, achieving both high optical modulation and robust cycling stability remains a challenge. This study presents a cost-effective and straightforward cathodic electrodeposition method to fabricate amorphous tungsten oxide dihydrate (WO₃·2H₂O) films using a precursor solution primarily composed of monomeric diperoxotungstate. The open framework and interlayer structural water in WO₃·2H₂O enable exceptional dual-band electrochromic performance at super-low switching potentials (-0.5 V for full coloration and 0.5 V for full bleaching) in a 1.0 M LiClO₄/propyle
