The performance of nanostructured devices depend significantly on the morphology and structure of the used nanostructures. We report the hydrothermal synthesis of high quality 2D ZnO nanostructures and the fabrication of ultraviolet (UV) sensors based on single 2D ZnO nanostructures. The grown nanostructures are characterized using SEM, STEM, SAED, and XRD. The single 2D ZnO nanostructure UV sensor demonstrates high photosensitivity of 980 and speed of response and recovery of 19 and 25 s, respectively. The high performance is attributed to the high quality of the ZnO 2D crystals and its high surface to volume ratio.
