Annotation For the first time one-dimensional nanostructured zinc-oxide arrays (1D ZnO) which are suitable for optoelectronics and nanophotonics were obtained by pulsed cathodic electrodeposition method adapted for large-scale production from aqueous solution without using of surface-active modifiers for growth and subsequent thermal treatments. The low defect density and high optical material quality were confirmed by intensive photoluminescence (PL) in ultraviolet (UV) region. The sharp high peak of UV photoluminescence of nanostructured ZnO array electrodeposited on silicon substrate indicates its effective radiative recombination. The UV PL is explained by weak crystal texture (0001), insignificant compression microstrains and residual stresses which were revealed for these 1D ZnO arrays.
