Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Molybdenum oxide (MoO₃) mixed tungsten oxide (WO₃) thin films have been prepared by hybrid physico‐chemical synthesis involving microwave assisted sol‐gel synthesis (MW‐SGS) of WO₃ followed by vacuum evaporation of MoO₃ on fluorine doped tin oxide (FTO) coated glass substrates. The optostructural and morphological properties of WO₃ thin films with different thickness of MoO₃ layer were investigated and studied for enhanced electrochromic coloration. The electrochromic performance of these samples was studied in LiClO₄/PC as electrolyte for Li⁺ insertion/extraction. Colorimetric analysis was done to define the colors in the bleached and colored states in terms of <italic>L</italic>_ab* values and <italic>xy</italic> chromaticity diagram. Enhancement in electrochromic properties in terms of optical modulation (Δ<italic>OD</italic>), coloration efficiency (<italic>CE</italic>) and switching time (<italic>t</italic>_b and <italic>t</italic>_c) was studied and reported.</p> </abstract>
