“…[ 11 ] It plays an important role in a wide range of applications including in biological detectors, light‐emitting diodes, sensors, and photocatalysts. [ 12,13 ] To date, sulfide semiconductors have been synthesized using various methods such as solvothermal [ 14 ] and hydrothermal routes, [ 15,16 ] solid‐state methods, [ 17 ] chemical vapour deposition (CVD), [ 18 ] liquid crystal templating, [ 19 ] ultrasonication methods, [ 20 ] simple chemical precipitation, [ 21 ] and high temperature thermolysis of organic precursors. [ 22 ] Among them, one of the most popular techniques is the solvo/hydrothermal route, which presents many advantages such as low production cost, echo‐friendliness, easy of process, and cleanliness.…”

Copper sulfide and zinc sulfide nanostructures were synthesized using a solvo/hydrothermal method and a thio Schiff base ligand, N‐benzylidene ethanethioamide, as a source of sulfide ions. The effects of different synthesis parameters including the type of solvent, temperature, and duration of reactions on the morphology of the CuS and ZnS products were investigated using field emission scanning microscopy and transmission electron microscopy, respectively. The structural aspects of the samples were characterized using powder X‐ray diffraction, Fourier transform infrared spectroscopy, and energy dispersive X‐ray analysis. The optical properties of the samples were studied through their optical absorption and photoluminescence spectra. The photocatalytic ability of the as‐synthesized sulfides was explored by studying the colour removal of methylene blue under ultraviolet light irradiation.

“… 9 Zinc sulfide (ZnS) has been utilized as a photocatalyst semiconductor NP due to its high thermal resistance, biocompatibility, and cost-effectiveness. 16 Owing to its high bandgap (3.6 eV), ZnS fails to absorb visible light. Its rapid electron–hole pair recombination can also result in a photo-corrosion reaction.…”

“…Despite the advantages of the synthesis methods, several limitations such as high temperature requirement, need for expensive and toxic organic precursors and the requirement of activation agent for the precursors makes the procedure unattractive. However, regardless of the different synthesis method and applications of zinc sulfide [5], [8], [18]- [26], little or no information has been provided on how to tune the degree of sulfur vacancies in the synthesis of ZnS. To the best of our knowledge, no research has studied how varying reaction conditions can tune the degree of sulfur vacancies in ZnS.…”

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.
