Tin oxide was prepared by chemical methods and then doped with different weight ratios of vanadium 2wt% and 4wt%. The structural, morphological, and optical properties were studied. It was found that all the recorded films had a polycrystalline diffraction pattern and that the predominant reflection was (111) plane. The doping processes resulted in the improvement of crystalline structure and the disappearance of a number of secondary reflections and the direction of the film in a single crystalline pattern, thus reducing the values of energy gap and percentage transmittance. The morphological properties were studied by converting the three-dimensional images into graphic drawings to enable us to easily calculate surface parameters.
