Abstract:Background:
In this work, CdS thin films were synthesized by sol-gel method (spin coating
technique) on glass substrates to investigate the optical behavior of the film.
Methods: Different substrate spin coating speeds of 2400, 3000, 3600 rpm and different Ni
dopant concentrations of 0 wt.%, 2.5 wt.%, 5 wt.%) were investigated. The optical properties of
thin films such as refraction index, extinction coefficient, dielectric constant and optical band gap
energy of the layers were discussed using spectroscopic … Show more
