Electrochromic Performance of V(2)O(5) Thin Films Grown by Spray Pyrolysis

A new approach regarding the development of nanostructured V(2)O(5) 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(2)O(5) films were characterized by X-ray diffraction, scanning el...

Sumario:A new approach regarding the development of nanostructured V(2)O(5) 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(2)O(5) 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(2)O(5) films with large active surface for electrochromic applications.
