“…This means that the thicker films have less defect concentrations (bigger grain size and fine grain boundary). The behavior of increasing the resistivity with average grain size agrees with other reported work [33] but does not agree with other studies of ZnS film deposited by ultrasonic spray pyrolysis [19,20]. The increase in the film thickness leads to an improvement of the crystalline quality.…”

Lead sulfide thin films were prepared by chemical bath deposition (CBD) on both glass and Si (100) substrates. XRD analysis of the PbS film deposited at 25°C showed that the prepared films have a polycrystalline structure with (200) preferential orientation. Larger grains could be obtained by increasing the deposition time. The prepared films were also chemically characterized using X-ray photoelectron spectroscopy (XPS), which confirmed the presence of lead and sulfur as PbS. While energy dispersive X-ray spectroscopy (EDX) technique was used to verify the stoichiometry of the prepared films. Atomic force microscopy (AFM) was used to study the change in the films’ morphology with the deposition time. The effect of the deposition time, on both optical transmittance in the UV-Vis-NIR region and the structure of the film, was studied. The obtained results demonstrated that the optical band gap decreased when the thickness increased.

“…Hence, our product is a stoichiometric film. Films with same stoichiometry were also acquired by different techniques, such as ultrasonic spray pyrolysis [15] and electron beam evaporation [16]. For further investigation of the chemical composition of the product, XPS scan of the sample was performed (Fig.…”

“…Several methods have been used to prepare ZnS films by different research groups [11], such as magnetron sputtering [12,13], pulsed laser deposition, chemical bath deposition (CBD) [14], ultrasonic spray pyrolysis [15], electron gun evaporation [16] and thermal evaporation [12]. The latter is particularly interesting, due to its simplicity and cheapness.…”

Zinc sulfide (ZnS) and zinc sulfide/lead sulfide (ZnS/PbS) nanorods were grown on glass substrates using a thermal evaporation method. The morphology of the prepared samples has been studied by transmission electron microscopy (TEM), field-emission scanning electron microscopy (FE-SEM) and Scanning Electron Microscopy (SEM). Both differences and similarities in morphology between the samples have been discovered. In the ZnS/PbS sample, ZnS nanorods were formed with diameter less than 50 nm and length between 2000 and 3000 nm. The pure ZnS sample has dense structure and its thickness was about 200 nm. Samples were studied in detail using energy-dispersive X-ray spectroscopy (EDX). The surface chemical compositions of the samples were confirmed by means of X-ray photoelectron spectroscopy (XPS). The determination of the crystal structure using the X-ray diffraction revealed that two phases of ZnS, blende and wurtzite, are present in the sample after adding Pb, while only blende is identified in the pure ZnS sample.

“…These doping processes provide photoluminescence bands in different regions such as in orange region by Mn, green region by Eu and blue region by Cu doping (Ebrahimi, Yarmand & Naderi 2019;Wei et al, 2018;Mishra, Ojha & Khare 2018). ZnS thin films were grown by many researchers using different techniques such as chemical bath deposition (CBD), successive ionic layer adsorption and reaction (SILAR), sol-gel, RF magnetron sputtering, pulsed laser deposition and ultrasonic spray pyrolysis (Yang, Li & Zeng, 2019;Akhtar et al, 2017;Patel et al, 2010;Alnama, Abdallah & Kanaan, 2016;Hennayaka and Lee, 2013). In this study, Ultrasonic Spray Pyrolysis method was used to coat ZnS thin films on glass substrates using Zn (Zinc), S (Sulfur) and Ni (Nickel) sources.…”

This study presents the production of pure and different amounts of Ni-doped (4, 8, 12%) ZnS films on microscope glass substrate at 4005°C substrate temperature with Ultrasonic Spray Pyrolysis Technique and the effect of Ni doping on some physical properties of pure films. X-ray diffractometer (XRD), UV-Vis spectrophotometer, two-probe method and atomic force microscope (AFM) were used to analyze the structural, optical, electrical and surface properties of all films, respectively. XRD patterns contains broad peaks showing a low crystallinity level for the films. Ni doping caused ZnS films to have high absorbance values through the visible spectrum. Optical band gap energy values of ZnS:Ni thin films were determined to be between 3.71-3.96 eV. Two-probe measurements revealed that the electrical conductivity values of ZnS films increased significantly depending on the Ni doping. AFM results showed that the films have an almost homogeneous distribution with a rough surface. No significant change was observed for the surface properties of the films due to the Ni doping. As a result of all analyzes; it was seen that Ni doping has an important effect on the optical and electrical properties of ZnS films, without modifying the crystalline structure or surface texture.
