Abstract
By a sol-gel followed with spin coating technique, Sb doping thin films with varying coating thicknesses have been successfully synthesized. Crystal size determined by XRD analysis of Sb doping ZnO thin films with coating thickness variations ranging from 17.77 nm to 27.98 nm and a hexagonal wurtize-shaped crystal structure. The SEM analysis revealed that the thickness of the Sb doping ZnO thin films varied between 6.5 and 10.4 µm. The surface of Sb doping ZnO thin films reveals that the layer thickness increases as the crystallite grains appear round, nearly uniform, and dense, and there are almost no visible pores. UV-Vis analysis revealed that the transmittance value of all Sb doping ZnO thin films was greater than 80%. The energy band gap for all samples was 3.20 eV, and the thickness of Sb doping ZnO thin film had no effect on the energy band gap value.
