Control of Morphology and Properties of Zinc Oxide Nanostructures Manufactured by Pulsed Electrochemical Deposition.

In this paper we study ways to control the morphology and properties of zinc oxide nanostructures, which are produced by pulsed electrochemical deposition The effect of mixing of electrolyte, changes in the shape of rectangular pulses of the cathode-substrate potential, as well as the electrolyte composition and duration of the pulsed electrodeposition process on the morphology, crystal structure and optical properties of nanostructured ZnO arrays has been demonstrated. The reasons for the formation by pulsed cathodic electrodeposition without introducing of surfactant growth modifiers into the electrolyte of ZnO arrays, consisting of regular hexagonal nanoplates and their stacks with vertical or horizontal arrangement with respect to the substrates, layers of paraboloid ZnO nanostructures, as well as one-dimensional arrays of zinc oxide, oriented perpendicular to the substrate were analyzed. It was demonstrated by the atomic force microscopy the manufacture of these nanostructured zinc oxide arrays. By the X-ray diffraction and optical spectroscopy the structure and properties of ZnO nanostructures fabricated by pulsed electrochemical deposition were studied. [ABSTRACT FROM AUTHOR]
