Morphology and optical properties of zinc oxide nanostructures synthesized by the methods of thermal and discharge sputtering

Zinc oxide nanostructures are obtained by the methods of electrothermal and discharge sputtering in gaseous and liquid media. Structure and phase peculiarities of synthesized samples, as well as morphology and luminescence properties of synthesized structures with and without doping are examined. The luminescence spectra of the deposited zinc oxide nanostructures have characteristic luminescence maxima (at λ = 380 and 520 nm) associated with exciton emission and defects in nanocrystals, respectively.
