Reproducible p-type Ag–S co-doped ZnO (ASZO) films were grown on glass substrate by a modified hydrothermal method, where reaction solution is separated from alkali solution and O2 is removed from autoclave to avoid deoxidation of Ag+ and oxidation of S2− in the solution. It is found that the Ag substitutes for the Zn in monovalent state (AgZn+) and the S for the O in bivalent state (SO2−) in the...
As-doped sub-micron ZnO rods were realized by a simple thermal diffusion process using a GaAs wafer as an arsenic resource. The surface of the sub-micron ZnO rods became rough and the morphology of As-doped sub-micron ZnO rods changed markedly with increasing diffusion temperature. From the results of energy-dispersive X-ray spectroscopy, X-ray diffraction and photoluminescence, arsenic elements were...
