Tailored Nanostructures of WO3: Unveiling Enhanced Electrochromic Performance through Structural and Morphological Optimization

Tungsten oxide (WO3) nanostructures have gained significant attention for their potential applications in electrochromic devices due to their unique structural, morphological, and optoelectronic properties. In this study, we present a comprehensive investigation into the tailored synthesis of WO3 nanostructures with controlled structural features and morphological properties. The hydrothermal method was used to synthesize WO3 with different strategies, to engineer the nanostructure growth and morphology of WO3. Characterization techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD) are employed to elucidate the structural and morphological properties of the synthesized nanostructures. Moreover, electrochemical analysis is used to evaluate the electrochromic performances of the WO3 nanostructures to get a deeper understanding of their optical modulation, coloration/bleaching capabilities, etc. Overall, our findings highlight the importance of tuning the structural and morphological properties of WO3 nanostructures for achieving enhanced electrochromic performance, hence revealing the way for their potential usage in displays, smart windows, printable smart QR codes and other optoelectronic devices.
