Electrosynthesis and optical modeling of ZnO nanostructures

Optical modeling was applied for obtaining absorbance spectra and band gap values for differentmorphology of ZnO semiconductor. In optical modeling, the relative permittivity scalars of zincoxide coral like nanorods were calculated using the Bruggeman homogenization formalism. ZnOnano rods (ZONRs) as a nucleus layer were fabricated on the Indium Tin Oxide (ITO) by chronoamperometry(CA) in aqueous solution containing different concentration of zinc nitrate. Reductionof nitrate anion is a good resource for hydroxyl ion that with zinc anion results ZnO. Theorientation and morphology of both the nucleus layer and successive coral like ZONRs were analyzedusing X-ray diffraction (XRD).Keywords: Optical modeling; ZnO; chronoamperometry; coral like nanostructure.
