ZnO nanostructures must be added to improve the morphological and optical properties of optoelectronic devices for nanotechnology applications. In this study, 1%, 5% and 10% Co elements were added to ZnO nanomaterial and samples were produced by sol gel spin coating method. When the samples were produced, coating process was carried out using a rotation speed of 1500 rpm and a rotation time of 25 seconds. Coating process repeated 5 times. Two-dimensional and three-dimensional images of the films produced using Atomic Force Microscopy (AFM) were analyzed. The surface morphology and surface roughness of the films were examined with the help of these analyzes. The transmittance and absorption spectra of the produced films with UV-VIS spectroscopy were taken and the optical properties were examined by calculating the optical band gap. While the increase in roughness values increased with the addition of co, the decrease in the transmittance values of the optical band gap range increased up to 10% Co contribution and a 10% Co contribution decreased. <br /> </p> <p> </p>}, number={1}, publisher={Fırat University}
