“…ZnS NPs have recently drawn special attention because of their abundance, low cost, good stability, non-toxicity, physical and chemical stability, good light UV absorption, and high catalytic efficiency [18][19][20]. Several chemical and physical methods are widely used to elaborate ZnS NPs like pulsed laser deposition [21], solvothermal [22], sol-gel [23] and hydrothermal [24]. Researchers have developed a new approach to synthesize functionalized ZnS NPs using capping agents.…”

This study aims at synthesizing zinc sulfide (ZnS) thin films using spray pyrolysis method. The effect of the Zn concentration on the physical properties of ZnS is investigated using X-ray diffraction (XRD), scanning electron microscope (SEM), UV-Vis spectrophotometer, photoluminescence (PL), and Raman spectroscopy. XRD shows a preferential orientation along the (111) direction corresponding to the ZnS cubic structure. Based on the XRD results, it is seen that low zinc concentrations compared to sulfur content can increase the crystalline quality of films. Raman spectra confirm the presence of the ZnS cubic structure observed by XRD and show the presence of sprayed ZnS vibrational modes for all films. PL emission spectrum of ZnS confirms the presence of Zn and S atoms at all molar concentrations. SEM reveals densely packed and uniformly distributed grains with precise shapes. The elemental analysis confirms the growth of stochiometric Zn/S ratio. The optical analysis shows a high transmittance around 88% in the visible range of the solar spectrum with optical band gaps varying from 3.4 to 3.6 eV. These properties are interesting and show that ZnS thin films can be used as buffer layers in thin film solar cells applications.

“…ZnS nanoparticles can be considered the best host for adjusting the optimal band gap engineering for the electric applications of effective optoelectronic devices [ 10 , 11 ]. Various techniques including Microwave [ 12 ], Hydrothermal [ 13 ], solid state [ 14 ], and sol-gel [ 15 ] have been used to synthesize ZnS nanostructured materials. Nanostructured materials are characterized as materials comprising hundreds to thousands of atoms.…”

Doping ZnS nanoparticles with different metal and/or non-metal ions is one of the ways to improve their properties. That is because dopants introduce strain into the lattice of the ZnS nanoparticles. The influence of Ti on the ZnS nanoparticles was investigated on the structural properties, optical properties, and also electrical impedance spectroscopy (EIS). The presence of Ti in the crystal lattice of the ZnS introduced strain into the crystal structure, hence causing a lattice expansion and reducing the crystallite sizes of the ZnS nanoparticles. Ti doping was observed to increase the energy band gap of ZnS nanoparticles and also reduce the charge carrier recombination. Doping Ti into ZnS was observed to decrease the charge transfer resistance of ZnS nanoparticles with an increase in dopant concentration indicating an improved charge transfer mobility owing to the presence of strain in the crystal lattice.
