Özet: In this study, undoped and Cd doped SnO thin films at different atomic rates (0, 2, 4 and 6%) were synthesized by the Sol-Gel method. The changes in the opto-electrical properties of the samples produced with Cd dopant were investigated by means of the UV-VIS-NIR spectroscopy. The effect of Cd doping on the optical properties of SnO films was investigated by spectrophotometric measurements. Optical constants (refractive index, n, and absorption index, k) of the samples were obtained in the wavelength range of 300-800 nm. Dispersion parameters were determined and discussed according to the single oscillator model. The optical band gaps of the samples were calculated using Tuac equation. It was observed that Eg values of the samples increased from 3.57eV to 3.60 eV depending on the Cd dopant. As a result of the investigations, it was determined that Cd doping has significant effects on the optical properties of SnO films and the produced samples can be used in transparent conductive electrode applications, optoelectronic devices, and sensor production.
