Abstract
CdS thin films were prepared by the chemical bath deposition technique. Annealing in air at different temperatures (300, 350, 400, 450, and 500)°C at constant time of 30min, also for different times (15, 30, 45, 60, and 90) min at constant temperature (300°C) is achieved. The CdS films showed, on average, 20% reflectance. The transmittance ranged between 80–92% for the films annealed at 60 and 45 min. On average, the refractive index of the CdS is 1.2 and the band gap is 2.4eV, the wide band gap semiconductor has a wide range of applications in areas including photocells and other photoconductive devices.
