Optical Emissions of Zn and ZnO in Zn-ZnO Structure Synthesized by Electrodeposition with Aqueous Solution of Zinc Nitrate-6-hydrate

Abstract

Both hexagonal zinc and wurtzite zinc oxide were deposited on p-type silicon substrate by the electrodeposition with an aqueous solution of zinc nitrate-6-hydrate near room temperature. Zinc dominates the growth at higher current density, and zinc oxide dominates the growth at higher deposition temperature. The optical emission from zinc and zinc oxide nanostructures are observed from microphotoluminescence spectra.
