AbstractThe in-situ aqueous synthesis of ZnO nanorods doped with Sb is presented. To control the inclusion of Sb into the ZnO nanorods structure ethylene glycol (EG) is added to the reaction solution. The addition of EG reduces the rate at which Sb is included in the ZnO rods and produces nanorods with a morphology that is similar to the undoped rods. This is contrary to the rods produced with Sb in the absence of EG which produce a less well ordered structure. An I/V curve taken from individual rods indicates a change in the diode behaviour. The change in I/V behaviour is associated with a change from the natural n-type behaviour of ZnO to a p-type behaviour due to the Sb doping.

We have successfully synthesized Fe-doped ZnO nanorods by a new and simple method in which the adopted approach is by using ammonia as a continuous source ofOH-for hydrolysis instead of hexamethylenetetramine (HMT). The energy dispersive X-ray (EDX) spectra revealed that the Fe peaks were presented in the grown Fe-doped ZnO nanorods samples and the X-ray photoelectron spectroscopy (XPS) results suggested that Fe3+is incorporated into the ZnO lattice. Structural characterization indicated that the Fe-doped ZnO nanorods grow along thec-axis with a hexagonal wurtzite structure and have single crystalline nature without any secondary phases or clusters of FeO or Fe3O4observed in the samples. The Fe-doped ZnO nanorods showed room temperature (300 K) ferromagnetic magnetization versus field (M-H) hysteresis and the magnetization increases from 2.5 μemu to 9.1 μemu for Zn0.99Fe0.01O and Zn0.95Fe0.05O, respectively. Moreover, the fabricated Au/Fe-doped ZnO Schottky diode based UV photodetector achieved 2.33 A/W of responsivity and 5 s of time response. Compared to other Au/ZnO nanorods Schottky devices, the presented responsivity is an improvement by a factor of 3.9.
