【 摘 要 】

CdS/PbS and CdS/PbS capped with Ag thin layer thin films were organized by chemical bath deposition technique. The effect of silver layer on the optical properties (absorption and direct and indirect band gap) were investigated. It was observed from the absorption spectra of the thin films that the silver layer that deposited on the surface of film has a very important influence on the location of the absorption peak as well as the amount of the energy gap. The band gaps were found in the range 1.75 to 2.38 eV.
