“…These values are higher than experimental value of CdS [20,50]. Results are in good agreement with the findings reported in [31,40]. Most of dielectric properties appear in low energy (frequency) regions due to quantum confinement effects.…”

“…Experimental calculated value of refractive index is 2.38 at energy 1.96 eV (632.8 nm) while our DFT calculated values are higher than experimental value. Hence high value of refractive index of Ag doped CdS system emphasizes its use in optoelectronic devices [31,46,47].…”

“…They concluded that addition of Ag ions in CdS nanoparticles will not bring any remarkable change in nanocrystal [30]. Mochahari et al in 2017 [31] have observed increase in dielectric constant and refractive index which increases with increasing ion fluence. All experimental studies have been focused on nanoparticles of CdS [4] but theoretical study has not been presented yet which will demonstrate comparison of experimental and theoretical results.…”

Current research is a computational study on optical properties of Ag doped CdS based on the Perdew-Burke-Ernzerhof parameterized generalized gradient approximations. Observing change in optical properties under various concentrations on CdS:Ag system, by fixing supercell size is a focus of study using density functional theory. Computational formulation is done by substitution of Cd atoms with Ag atoms in host CdS lattice. Results reveal that optical properties are enhanced upon increasing dopant concentration. Optical absorption shows blueshift and increases in visible region. Coupling of S p and Ag s states are obvious from plots of density of states. However, Ag doping brings significant change in optical properties which may lead towards advocacy of CdS for optoelectronic devices.
