CdS thin films were prepared by the successive ionic layer adsorption and reaction (SILAR) method. The optical properties of these films have been investigated as a function of temperature. The band gap energy change, steepness parameter, and Urbach energy parameters were also investigated as a function of temperature. The band gap energies were calculated at 10 K and 320 K, as 2.427 and 2.377 eV for CdS thin film, respectively. Film morphology was characterized by scanning electron microscopy and XRD measurements.
