In this work we have prepared zinc oxide ZnO nanowires non doped
and doped (1,2,3) with deferent percentage of silver by the
electrodeposition technique on glass substrates "ITO".The as-prepared
samples are investigated via various characterization techniques, such
as X-ray diffraction, scanning electron microscopy (SEM) ,electrical
impedance spectroscopy (EIS) and photoluminescence(PL)
The experimental results have shown that the ZnO thin films
deposited are relatively uniform on the substrates. Structural analysis
by X-ray diffraction showed that the films deposited by the
association of this technique are wurtzite structure with a preferential
orientation along the <002> and SEM analysis revealed the surface
topography and morphology. Optical measurements have shown that
the deposited ZnO nanowires have a bandgap equal to 3 eV close to
that of single crystal ZnO 3.36 eV.
