Nanostructured RF sputtered hexagonal ZnO nano-pebbles based electrode material for energy efficient devices Available to Purchase

In the present work, we describe the synthesis and electrochromic (EC) properties of electrode material made of zinc oxide (ZnO) nano-pebbles. Highly ordered nanocrystalline nanoporous ZnO nano-pebbles electrode with crystalline hexagonal structure was synthesized on the ITO coated glass substrate using RF magnetron sputtering in a reactive atmosphere (Ar:O₂::2:3) at room temperature (RT). The EC behavior of the active electrode was analyzed using UV-Vis spectroscopy and cyclic voltammetry (CV). The cyclic Voltammogram revealed the highly reversible redox characteristics with good cyclic stability at least upto 500 cycles. The proposed architecture, {Glass/ITO/ZnO nano-pebbles/1MKCl/ITO/glass} was found to be electrochemically active and exhibits wide optical modulation (26%), high reversible process, and good cyclic stability. The cathodic coloration ZnO electrode may be a potential candidate for novel and cheap energy efficient device and provide the indoor comfort with financial benefits.
