Abstract
AbstractMolybdenum 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 Lab* values and xy chromaticity diagram. Enhancement in electrochromic properties in terms of optical modulation (ΔOD), coloration efficiency (CE) and switching time (tb and tc) was studied and reported.
