Based on the p-NiO/n-ZnO nanowire (NW) heterojunction structure, a high-performance ultraviolet (UV) sensor has been achieved in this work. The sputtered p-type NiO exhibited good coverage on the hydrothermally-grown n-type ZnO Nano-Wires (NW's). The devices with 250-nm-thick NiO obtained the highest UV light sensitivity (I UV /I Dark = 4.98; I Visible /I Dark = 3...
Here we report that the various Ce 4+ -doped ZnO nanorods can be successfully synthesized by electrochemical deposition route, which represents a simple, quick and economical method for the controllable growth of Ce 4+ -doped ZnO nanorods. The high-resolution transmission electron microscopy (HRTEM) and the selected area electron diffraction (SAED) both proved that the prepared Ce...
The high density and orientation-ordered ZnO nanorod bundles with wurtzite structures were prepared on Cu substrates by electrochemical deposition in solution of ZnCl 2 +tartaric acid at a temperature of 90°C. This approach is a unique and size controlled synthetic method for the large-scale preparation of ZnO nanorod bundles. Cyclic voltammogram measured in solution of the mixture of ZnCl...
