“…There are many deposition methods of ZnS thin films such as thermal evaporation method [6], ion assisted thermal evaporation [7], RF sputtering [8], spray pyrolysis [9], atomic layer deposition [10], electrochemical deposition [11], electron beam evaporation [12], SILAR [13], sol-gel [14], chemical bath deposition [15]. In this study, chemical bath deposition technique which is simple, safe and economic technique to deposit thin films has been used.…”

ZnS thin films were deposited onto glass substrates by chemical bath deposition (CBD) technique at different deposition temperatures (75, 80, 85, 90 °C) with non-toxic complexing agent tri-sodium citrate. Effects of deposition temperature on structural, morphological, and optical properties of thin films were investigated by using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and ultraviolet–visible spectroscopy, respectively. The XRD results show that all produced ZnS thin films have cubic structure. The calculated grain size values are between 13 and 26 nm. It was observed that the grain size values increase and crystallization of films improve as the deposition temperature increases. The FESEM images reveal that film surfaces are formed by almost homogeneously dispersed nanostructured particles. Optical characterization results show that ZnS thin films have high transmittance of about 80% in the range of 400–800 nm with band gap energy values between 3.52 and 3.65 eV. As the deposition temperature increases, the band gap energy values increase. According to these results, it was observed that the structural, morphological, and optical properties of ZnS films vary depending on the deposition temperature.

“…5. The optical band gap (E g ) values obtained from these Tauc plots are presented in Table 3 The band gap was found to decrease with increasing molar concentration, as given in Table 3; for higher concentrations of thiourea, the energy gap has decreased considerably from that of the bulk (3.7 eV) [16,37,38].…”

“…The crystallite size was found to be increased with the increased molar concentration of thiourea, as given in Table 2. According to the reports of Bacha et al [16], the glass substrate had a greater disorder which had influenced the optical band gap of the prepared film. In the present work, all the ZnS thin films were deposited on the glass substrates, so that; the reduction in the optical band gap can be well noticed with the concentrations.…”

“…Among them, the chemical bath deposition (CBD) technique is more advantageous, since, it has simple methodology, ability to tune the optical properties of the films, and large area deposition [1]. The effect of different substrates on the ZnS thin films was studied by Bacha et al [16] and Daranfed et al [17]. Lashgari et al [18] investigated the electronic and optical properties of 2D ZnS and compared them with Wurtzite phase 3D ZnS using DFT calculations.…”

Nanocrystalline ZnS thin films incorporated onto glass substrates by chemical bath deposition method were investigated by X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), UV-Visible Spectroscopy (UV-Vis), Photoluminescence (PL), and Raman Spectroscopy (FT-R) studies. The influence of thiourea on the structural and optical properties of ZnS films was discussed in detail. The X-ray diffraction patterns confirmed the rhombohedral structure of ZnS thin films. AFM measurements indicated the nano carpet-like surface morphology variation in film with influence of thiourea. The optical absorption studies in the wavelength range of 200-800 nm showed that the band gap energy of ZnS has decreased from 3.69-3.36 eV, as thiourea varied from 0.2-0.8 M. The PL spectra divulged a shift near band edge emission around 360 nm, when thiourea concentration was increased. The Stokes shift calculations from PL emission spectra supported the relative intensities estimated from PL energy band spectra and showed a dependable repeatability for different molar concentrations. The Zn-S complexes were identified in the Raman spectra and the Raman spectral shift for 0.6 M composition of thiourea, which was found to be appreciable for ZnS thin films. The characterization studies clearly exposed the effect of thiourea onto the chemically deposited ZnS thin films.

“…The optical band gap energy of ZnS particles were calculated by plotting graph (αhν) 2 versus hν [16][17][18][19]. The band gaps were determined by the intercept of straight line portion of the (αhν) 2 versus hν graph on the hν axis.…”

Zinc sulfide particles layer were grown on FTO glass and stainless steel substrates by electrode position technique from aqueous solution that contained 0.1 N zinc sulfate, 0.1 N sodium thiosulfate and 0.1 N triethanolamine was used as complexing agent. The deposing potential was analyzed by cyclic voltammetry technique. The ZnS particle growth was studied in the range of deposition time from 10 to 40 minutes. The thickness of layer was found to be the highest, 3.92 µm, at 20 min. The various percentage of complexing agent, pH of solution and thicknesses of film were characterized by scanning electron microscope (SEM) and UV-Visible spectrophotometer. The effects of complexing agent, pH of solution and thickness of layer on morphological and optical properties of ZnS were investigated. The Electrical resistivity of ZnS was found thickness dependent. The Chemical Composition of ZnS particles analysed by EDAX (Energy Dispersive Analysis by X-ray).
