Nanocrystalline and monophasic thin films of metal chalcogenide (FeS, ZnS) and oxide (ZnO) by chemical bath deposition (CBD)

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 subs...

Description
Summary: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 14 nm for nano‐flakes of FeS, 9.09 nm for nanoparticles of ZnS, and 49 nm for nanorods of ZnO. The average values of the band gaps were found to be 1.97, 3.43, and 3.74 eV for FeS, ZnO, and ZnS thin films, respectively. These nanostructured semiconducting materials have wide applications in advanced optoelectronic devices.
