Abstract
A simple two-step aqueous method was employed to grow NiO nanostructures on ZnO/sapphire at low temperature. The obtained NiO nanostructures were uniformly distributed on the surface of ZnO/sapphire substrates and showed sheet-like structures. Meanwhile, ultraviolet (UV) photodetector based on NiO/ZnO heterojunction was fabricated by a simple way. The obtained UV detector based on the NiO nanosheets/ZnO heterostructure showed excellent UV sensing properties due to the increased surface and local [Formula: see text]-[Formula: see text] junction area. It will facilitate greatly the fabrication of large-scale NiO/ZnO heterostructure with relatively low cost at remarkably low temperature.
