PbS thin films were grown on glass and GaSe crystal substrates by chemical bath deposition and their structural, morphological, optical, and electrical properties were investigated. PbS films grew in cubic structure with lattice constants equal to 5.9315 Å and 5.9362 Å for films grown on glass and GaSe crystal, respectively. The band gaps of the PbS films were determined to be 1.60 eV. The long wavelength tails of absorption spectra showed exponential dependence on the incident photon energy according to the Urbach-Martiensen model. Electrical properties of PbS films were investigated by the van der Pauw method, which showed that PbS …

PbO-PbS thin films were deposited on glass substrates using the chemical bath deposition (CBD) technique. PbO thin films were deposited from the solution of lead nitrate (Pb(NO_3)_2) and sodium hydroxide (NaOH). Ethylenediaminetetraacetate (EDTA) served as the complexing agent. Some of the PbO films were used as substrate for the deposition of PbS. The PbS was deposited from alkaline solution of lead nitrate and thioacetamide. Triethanolamine was used as the complexing agent. Some of the films were subjected to thermal treatment after deposition. Energy dispersive X-ray fluorescence analysis confirmed the presence of Pb and S in the PbS thin films, while …
