Deskripsi

A new approach regarding the development of nanostructured V<sub>2</sub>O<sub>5</sub> electrochromic thin films at low temperature (250 °C), using air-carrier spray deposition and ammonium metavanadate in water as precursor is presented. The obtained V<sub>2</sub>O<sub>5</sub> films were characterized by X-ray diffraction, scanning electron microscopy and Raman spectroscopy, while their electrochromic response was studied using UV-vis absorption spectroscopy and cyclic voltammetry. The study showed that this simple, cost effective, suitable for large area deposition method can lead to V<sub>2</sub>O<sub>5</sub> films with large active surface for electrochromic applications.
