Structural Electrochromic Properties of WO3and CeO2/WO3films for Smart Windows Applications G V Ashok Reddy, Kilari Naveen Kumar, Sheik Abdul Sattar, Hitha D Shetty, Kotian Akshata Chandrakant, N Lakshmi Priya Journal of Physics Conference Series, 2025 A template-free hydrothermal process was adopted for the direct growth of CeO2 nanorods on fluorine-doped tin oxide (FTO) substrates. These nanorod films were then coated with optimized tungsten oxide (WO3) layers through sputter deposition. For electrochromic device (ECD) fabrication, The WO3 layers were sputter-deposited while maintaining an oxygen partial pressure of 8 × 10−4 mbar. To assess their properties, the WO3 films deposited on CeO2 nanorods were analyzed through structural, morphological, optical, and electrochromic studies employing XRD, SEM, FTIR, Raman, transmittance spectroscopy, and CV measurements. In comparison with pristine WO3 films, the CeO2 NRs/WO3 composite films demonstrated enhanced electrochemical performance, where the diffusion coefficient was estimated as 7.45×10−11 cm2/s. Moreover, the CeO2/WO3 films exhibited a high coloration efficiency of 14.83 cm2/C, highlighting their potential in electrochromic applications. This work provides insights into the influence of CeO2 nanorods on the electrochemical characteristics of WO3 films, supporting the development of efficient dopantengineered materials for smart window technologies.
