AbstractIn this article, we report feasibility of composite hydroxide-mediated (CHM) approach for the synthesis and doping of Cu1-xZnxO (x=0%, 3%, 6% and 9%) nanomaterial. The proposed method offers a low cost, low temperature and environmentally friendly approach to preparing doped nanomaterials in a feasible and cost- effective route. Further, we investigate the effect of incorporated Zn +2 on the properties of produced Cu (II) O nanostructures. The X-ray diffraction analysis confirms formation of the single-phase monoclinic Cu (II) O and incorporation of Zn at the Cu-lattice sites. The crystalline structure is improved and the average grain size has increased from 85.32 nm to 124.86 nm. FTIR spectroscopy shows characteristic vibrational peaks of the Cu (II)-O bonding which confirms formation of the Cu (II) O. SEM micrographs reveal interesting flower like dense features with morphological peculiarities and seems to strongly depend on the content of the incorporated Zn +2 . The UV- visible spectra are measured to study the direct bandgap of the prepared nanomaterial. The direct bandgap found to be in the range of 3.73 - 3.89 eV. The method seems experimentally friendly and provides a feasible and a high productive fast synthesis route for the doped oxide nanomaterials in a single step with tunable properties for the research purposes. However, the method still requires further investigation to finely control doping for the desired properties of a nanomaterial and to give a potential avenue for further practical scale-up of the production process and applications of novel devices based on doped nanostructures.
