“…Some of the parts of these devices include photo-detectors, optical amplifiers, and optical modulators, in addition to sources like light-emitting diodes (LEDs) and laser diodes. With the aid of these tools, photons may be produced, modulated, detected, and switched just like electrons in an electrical circuit [18].…”

“…Numerous research teams have reported their success in growing thin films using a range of techniques, including spray pyrolysis, solvothermal synthesis, ion beam assisted coating, chemical bath deposition, DC magnetron sputtering, spray pyrolysis, vacuum evaporation, thermal evaporation, SILAR, molecular beam epitaxy, and electrodeposition. In the current experiment, SrS and SrS/Ag material was deposited at room temperature using the electrodeposition approach since it offers comparative advantages over other methods in terms of economy, convenience, and ability to deposit vast regions of films [15][16][17][18][19][20][21]. It is extensively used to deposit different metal chalcogenides and is regularly employed with electrically conductive materials such conductive polymers, alloys, and metals.…”

In the research electrochemical deposition technique was use in deposition of undoped SrS and doped SrS with silver were 0.01 mol of thioacetamide (C2H5NS), 0.1 mol of strontium chloride hexahydrate (SrCl2.6H2O), and 0.01 mol of silver nitrate (AgNO3) were utilized as the cationic, anionic, and dopant concentrations. The XRD spectra of the SrS and SrS doped silver showed prominent crystalline peaks at angles of 26.69°, 37.97°, 51.39°, and 65.56° for SrS and 26.42°, 33.42°, 37.98°, and 51.32° for SrS/Ag, respectively, with corresponding diffraction planes (111), (112), (200), and (211). However, the diffraction pattern shows that the peak intensity increases as the deposition voltage increases. The undoped SrS material morphology has a clove-like substance with precipitate; the large nano grain on the substrate's surface exhibits photon absorption but shows no traces of pinholes. When doped SrS is deposited at various precursor voltages, it forms uniform surfaces devoid of pinholes. The cell also penetrates the substrate being used for the deposition, as seen by the elemental makeup of the films. It was observed that SrS/Ag at 10V and 12V had little precipitate on the surfaces; this is because a carbon electrode was utilized, which tends to react with electrolyte at low voltages but does not do so at 14V. The films show that when the deposition voltage increased, the electrical resistivity decreased from 1.42 x 109 to 1.37 x 109 Ω.m and the thickness decreased from 125.02 to 123.025nm. This further led to an increase in conductivity from 7.04 x 108 to 7.29 x 108 S/m. It was discovered that the absorbance decreases as the electromagnetic radiation's wavelength grows and the deposition voltage rises. According to research done on the deposited material, its energy bandgap lies between 1.55 and 2.51 eV.
