Abstract ZnO/ZnS core-shell structured nanorods array has been successfully deposited on ITO substrate via water bath method, and then were characterized by using SEM, XRD and XPS. Results show that the surface of ZnO/ZnS core-shell nanorods array is rough composed of nanorods of 150 nm in diameter, which grown uniformly and densely on the surface of ITO substrate. The self-powered ultraviolet detector was assembled using the ZnO/ZnS core-shell nanorods array and Pt as the counter electrode, then the UV detection performance was investigated. The self-powered ZnO/ZnS heterojunction ultraviolet detector has good reproducibility and stability after multiple cycles of testing. In addition, the device also has a strong photoresponse and high photosensitivity to ultralow light intensity, and displays photoresponse switching behavior as the light intensity increasing. Compared with the self-powered ZnO nanorods detector, the self-powered ZnO/ZnS heterojunction UV detector has faster response with the rise time and decay time of 0.02 s and 0.03 s, respectively.
