Improving the electrical, magnetic and antibacterial properties of sol–gel spin coated ZnO thin films through (Sn + Mn) co-doping

Vanadium doped zinc oxide was deposited using a homemade electrospray technique. The structural, optical, magnetic, surface morphology and electrical studies were carried out using XRD, UV-vis-NIR spectroscopy, HRSEM, AFM, photoluminescence, VSM and Hall effect, respectively. The XRD results revealed that the addition of vanadium(V) does not affect hexagonal wurtzite structure in the films. Photoluminescence study implies the increase of oxygen vacancy on surface of the samples and the hexagonal plates like grains are found on the film surface and formation of cluster as doping percentage increases. Hall effect shows the remarkable improvement in carrier concentration, resistivity and mobility. The sheet resistance decreases to 59.5 × 102 Ω/2 for 4 at% of vanadium. All the samples achieved the transmittance above 80% in the visible region and optical band gap increases. The magnetic study shows that the enhancement of paramagnetic property and the study on the performances of the samples over the light intensity shows, the enhancement in the rate of decreases in resistance, which is higher than the undoped sample ware discussed.
