“…However, the high amount of zinc present in ZnS(B) account for the concrete nature of the morphology and the small grain size [32]. This may result in better wetting property and increased smoothness of the material [9]. Furthermore, it resulted in evenly distributed films and improved opto electronic properties like photo sensing as reported in our previous study [32].…”

“…The same pronounced intensity pattern was observed in the (220) and (311) plane for ZnS(B) and ZnS(C). For all the materials, widening of the peaks were detected which characterize nanocrystalline nature of the samples [9,12]. The average crystallite size of the samples as shown in Table 2 was obtained through the Scherer equation in Equation 3 [33] 𝐷𝐷 = 0.9𝜆𝜆 𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵 (3) where D is the crystallite size, λ is the wavelength of Cu-Kα radiation, 𝐵𝐵 is the full width at half maximum (FWHM) in radian and 𝜃𝜃 is the Bragg diffraction angle.…”

“…ZnS belong to a group of nanostructured metal sulfides that are attractive materials in electronic, optical, optoelectronic, energy and environmental applications [1]- [3] and they can be used in EM driven functions within the UV and visible range [4]- [6]. Also, they have been broadly examined due to their possible utilization in photo catalysis, solar cells, sensors, photoconductors, window material, and other light emitting functions [7]- [9]. We can trace the significant characteristics of these semiconductor nanomaterials to their chemical and phase composition, size and shape, surface chemistry, and defects [10].…”

In this work, a modified synthesis method was deployed to obtain nanocrystalline zinc sulfide from zinc acetate. By utilizing the hydrothermal and sol gel method, the influence of; reaction time, solvent and temperature control was used to tune the properties of zinc sulfide. Our results showed that ZnS obtained by sol gel in water + hydrothermal (ZnS (A)) typified formation of increased sulfur vacancies while an increase in reaction time resulted in decreased sulfur vacancies. The introduction of chemical defects in sol gel in methanol + KOH obtained ZnS resulted in lower grain size. We observed that crystallinity improved with increased reaction time and the introduction of KOH and methanol as solvent could shorten the reaction time required for improved crystalline property. Our result showed that reaction time influenced the dislocation density of the material to a greater extent than type of solvent used. The crystallite size estimated by Scherer formula was between the range 2.50–4.91 nm while the band gap energy of the ZnS samples were calculated in the range 3.8 eV- 4.6 eV. Utilizing this novel synthesis method can stimulate new directions in synthesizing ZnS crystals with options of choosing appropriate method for specific applications depending on properties to be traded off.

Utilizing these novel syntheses methods can stimulate new directions in synthesizing ZnS crystals with options of choosing appropriate method for specific applications depending on properties to be traded off.
