Altering the electrochromic parameters of all-organic device by the doping of different metal oxides

Abstract

The research presented investigates the electrochromic properties of various materials, including metal oxides and conducting polymers, for potential applications in smart optoelectronic devices. Methods such as sol-gel synthesis, drop casting, and co-precipitation were employed to synthesize these materials, followed by characterization using techniques like cyclic voltammetry, electrochemical impedance spectroscopy, UV-Vis spectroscopy, scanning electron microscopy, X-Ray diffraction and Raman spectroscopy. The study compares the performance of different doping materials in terms of color switching time, stability, color contrast, coloration efficiency and reversibility at two different wavelengths. Results show promising outcomes, particularly with zinc oxide and tungsten trioxide doping, demonstrating enhanced coloration efficiency and stability. Moreover, the investigation suggests avenues for further research, such as exploring alternative synthesis methods to optimize material properties for specific device applications. Overall, the study contributes to advancing the understanding and development of electrochromic device for diverse optoelectronic technologies.
