Abstract
ZnO:Sb thin films with varying antimony (Sb) doping have been successfully synthesized using the so;-gel spin coating method. The results of XRD analysis of ZnO:Sb thin films with varying antimony (Sb) doping show a hexagonal wurtzite crystal structure with crystallite sizes decreasing from 16.27 to 15.14 nm along with increasing antimony doping concentration. The results of UV-Vis analysis show that increasing antimony (Sb) doping concentration is accompanied by decreasing transmittance values and increasing absorbance values of ZnO:Sb thin films. The energy band gap value of ZnO:Mg thin films ranges from 3.38 to 3.41 eV.
