FeS, ZnS, and ZnO nanostructured thin films have been deposited by Chemical Bath Deposition (CBD), a simple and cost effective technique. These materials with different morphologies such as nano-flakes, nanoparticles and nanorods for FeS, ZnS, and ZnO, respectively were deposited onto the glass substrates. The crystallite sizes have been estimated from Scherrer's equation and were found to be 14nm for nano-flakes of FeS, 9.09nm for nanoparticles of ZnS, and 49nm for nanorods of ZnO. The average values of the band gaps were found to be 1.97, 3.43, and 3.74eV for FeS, ZnO, and ZnS thin films, respectively. These nanostructured semiconducting materials have wide applications in advanced optoelectronic devices.
