The scanning electron microscopic image (taken using a FESEM LEO 1530) shows the ZnO nanostructures on an indium oxide coated glass substrate deposited at 70oC by using a facile electrochemical deposition technique. A potentio-/galvanostat electrochemical workstation (CH Instruments 660A) was used to deposit the ZnO nanostructures by amperometry potentiostatically at -1.1 V (relative to the Ag/AgCl reference electrode) and a spiral platinum wire served as working electrode. An aqueous zinc nitrate [Zn(NO3)2.6H2O] solution was used as an electrolyte to prepare these ZnO nanostructures.
