“…Plasma treatment is a method of modifying the surface of a substrate that uses plasma to affect the structure of vegetation on this substrate. Plasma is an ionized gas consisting of charged particles (ions and electrons) [19]. Plasma treatment can affect the structure of lead sulfide in several ways, for example, by changing the surface of the substrate, the morphology can be changed.…”

In this work, the effect of the substrate surface on the formation of structured lead sulfide films is studied. For this purpose, the surface of single-crystalline silicon (100) was subjected to plasma treatment in a glow discharge in an argon atmosphere, at a working pressure of 1 Pa and a potential difference across the electrodes of 2 kV. Lead sulfide films were obtained on treated and untreated single-crystalline silicon surfaces by chemical deposition from an aqueous solution of lead nitrate, thiourea and sodium hydroxide at a temperature of 70°C for 30 minutes. The surface morphology, elemental composition, and crystal structure were studied by scanning electron microscopy, energy dispersive analysis, and X-ray diffraction, respectively. As a result, the films deposited on pretreated substrates have a distinctly different surface structure compared to films deposited on untreated substrates. Under the same synthesis conditions, the growth of crystals on the treated surface occurred predominantly along certain lines and were grouped into individual particles, while on the untreated surface a continuous film was formed. Thus, through plasma treatment, crystal growth can be controlled to create nanostructures.

“…Many fabrication method have been used to deposit PbS thin films, including solid vapor deposition [10], chemical bath deposition (CBD) [11], spray coated [12] , spin-coating [13], and electrodeposition [14] silver (Ag) was used as a coating for many semiconductors like CdS thin films [15], CdSe [16], and PbS [17] to reduce the health risk and toxicity of this material, which have no undesirable effects on humans Based on our prior research into CdS/Ag hybrid thin film optical qualities, we've worked to uncover the mechanism between the Ag layer and the PbS hybrid in the current manuscript, which we're submitting for publication here. Comparing optical properties of CdS film before and after Ag layer deposition were studied, emphasizing the significant reduction in energy gap as well as an increase in absorption.…”

The chemical bath deposition approach was used to arrange PbS and PbS coated with Ag thin layer thin films. PbS film was deposited at room temperature using thiourea and lead chloride as precursors. After the PbS film had been deposited, it was immersed in Ag precursors for 60 minutes at 50 C to coat its surface. In this study, we looked at absorbance in the 400-1000 nm range. The direct and indirect bandgaps were estimated using the Tauc method and yielded values between 1.3 and 1.45 eV. It resulted in increasing in bandgaps after coating with of Ag layer.
