摘要：

Optical constants of cadmium sulfide (CdS) thin films for different bath temperature were determined in the spectral range, 400 to 1200 nm from the optical absorption and transmittance measurements. X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM), techniques was used to determine the crystallite structure and morphology of the films. EDX images showed that a sample with 70 degrees C bath temperature had a stoichiometric composition. The crystallite size and microstrain were calculated using Williamson-Hall method. Optical study is performed to calculate the refractive index (n), extinction coefficient (k), optical conductivity (sigma), dielectric constant (real and imaginary), and optical band gap using transmission spectra.
