Zinc sulfide (ZnS) nanoparticles have evoked research interest because of its extensive band gap, thermal stability, and potential applications in optoelectronic, photocatalytic and sensing applications. This paper has also used a controlled chemical displacement route in synthesizing ZnS nanoparticles, which provides a less complex and inexpensive approach to particle preparation and better control over the process. Optimized reaction conditions were used to perform the synthesis in order to get phase-pure material with homogeneous nanoscale dimensions. The crystalline structure of the ZnS was ascertained through structural analysis, which established the crystal to be of ZnS with the prevalence of cubic crystals, and morphological analysis showed the presence of almost spherical nanoparticles with minimal agglomerates. The thermal characterization also showed that the synthesized ZnS nanoparticles showed high stability, thus making them suitable to the high temperatures and device-oriented purposes. An assessment on the effects of the synthesis parameters on crystallite size, surface morphology and thermal behavior was done systematically in order to develop clear structure-property relationships. Results indicate that the chemical displacement-based method allows high resolution in the nanoparticle design without involving complicated and energy-demanding preparation procedures. In general, this paper identifies chemical displacement synthesis as an effective and viable method of manufacturing ZnS nanoparticles with desirable structural stability, morphological conformity, and thermal stability, which in turn, allows their usage in demanding functional nanomaterials.
