The fabrication and characterization of a ZnO nanowired arrays ultraviolet photodetector (ZnO NW arrays PD) has been presented. The nanostructures used included well-aligned Nanowires on glass substrate by chemical bath deposition. The morphological, structural and optical properties of these nanostructures were investigated. The obtained ZnO NWs had a wurtzite structure and grew along the preferential [0001] orientation with a normal direction to the substrate. This results have been investigated by field emission scanning microscopy (FESEM) and X-ray diffraction (XRD) pattern. The optical properties of the ZnO thin film have been investigated by UV-Visible microscopy and photoluminescence (PL). The electrical properties which is investigated from current-voltage curve show a photoconductor with an ohmic contact under illumination, and the low dark current and 0.83 mA/W as the responsivity of a photoconductor.
