| Popis: | ZnO and Sb-doped ZnO nanostructures were synthesized using microwave assisted precipitation method. Thick films of prepared powders were fabricated using screen printing method. The X-ray diffraction studies show that the nanostructures are crystallized in the form of hexagonal Wurzite crystalline phase and Sb-doping does not change the structure of ZnO. The size of nanostructures decreases with increasing the Sb+3-doping. Field emission scanning electron microscope (FESEM) images show the change in morphology and size of nanostructures are changing with change in doping percentage of Sb+3. The UV-visible spectra shows the increase in band gap with increasing the Sb +3-doping percentage. The gas sensitivity of pure and Sb+3-doped ZnO nanostructures was studied. The gas sensitivity of the films was improved with the doping of 7% Sb+3 in ZnO. |
