electrosynthesis and optical modeling of zno nanostructures

optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of zno semiconductor. in optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the bruggeman homogenization formalism. zno nano 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. reduction of nitrate anion is a good resource for hydroxyl ion that with zinc anion results zno. the orientation and morphology of both the nucleus layer and successive coral like zonrs were analyzed using x-ray diffraction (xrd).
