PbS thin films were grown on glass substrates by chemical bath deposition (CBD) using lead nitrate, thiourea and sodium hydroxide in aqueous solutions at three different temperatures (22, 36 and 50 C). The microstructure and morphology evolution of the films were investigated using X-ray diffraction, scanning electron microscopy and atomic force microscopy. Optical properties were studied using UV-Vis-IR spectroscopy. The results indicate that temperature plays an important role in controlling the morphology and optical properties of nanostructured PbS thin films through changing deposition mechanism. The active deposition mechanism changed from cluster to ion-by-ion mechanism with an increase in deposition temperature from 22 to 50 C, and consequently, film properties such as morphology, optical absorption and preferred orientation changed completely.

“…The resulting films were uniform, homogeneous and well adhered to the substrate with dark surface. The suggested reactions are as follows (Tohidi et al, 2014;Osherov et al, 2007 Figure 1 shows the X-ray diffraction patterns for PbS thin The crystalline size of the deposited films for all the samples were calculated using Full Width Half Maximum data (FWHM) and Debye-Scherer formula and their grain size are in within the ranges of (12-27) nm (Chaudhuri et al, 2005;Abbas et al, 2011).…”

“…PbS thin films has direct optical bandgap that can be changed from 0.39 up to 5.20eV (Koao et al, 2014). PbS thin films have been deposited through various deposition processes such as electrodeposition (Osherov et al, 2007), spray pyrolysis (Rajashree et al, 2014;Thangaraju and Kaliannan, 2000), chemical bath deposition (Koao et al, 2014;Preetha et al, 2015;Garcia-Valenzuela et al, 2013;Fernandez-Lima et al, 2007), and successive ionic layer adsorption and reaction (Puiso et al, 2003;Gulen, 2014;Pawar et al, 2013).…”

The influence of dip times on the lead sulphide (PbS) thin films deposited on glass slide substrates via chemical bath deposition (CBD) technique using chemical precursors, nitrate, and thiourea, ) in alkaline medium at 300 K was investigated. The optical, structural and morphological studies were performed by UV-vis spectophotometry, X-ray diffraction (XRD) and scanning electron microscopy (SEM) respectively. The XRD showed films of cubic (galena), crystalline in nature with the preferential (111) orientation. The optical studies showed films of direct band gaps in the range of 1.59-1.65 eV.

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, whileRutherford backscattering was used to identify the composition of PbO thin films.The absorbance of PbO-PbS films was extremely high in the UV region and decreased exponentially with increase in wavelength. The transmittance increased sharply but almost linearly with wavelength from the mid-vis region, having a maximum percentage value of 21% at 1000 nm (NIR). Hence, PbO-PbS films are good materials for UV filters and glazing for creating warmth in rooms.The band gap of PbO-PbS films is in range 2.15-2.25 eV.
