Investigation of Structural, Optical and Antibacterial Activity of ZnS Nanoparticles

Zinc sulfide (ZnS) nanoparticles have been successfully prepared by sol-gel precipitation method. The successful formation of cubic structure is ensured by XRD analysis and Debye Scherrer's equation is used to determine the crystallite size which was found to be 36 nm for ZnS sample annealed at 200 degrees C. Surface morphology was studied using HRSEM as well as HRTEM and lattice parameters of the samples were obtained from SAED pattern which was found to have close resemblance to values attained from XRD pattern. Further elemental mapping of ZnS nanoparticles is confirmed by EDX studies. Further Kubelka Munk function was employed to estimate the band gap value which was seen lying within 3.58 to 3.64 eV. Further the antibacterial activity of ZnS is investigated and it is found to be an antibacterial agent of Escherichia coli and staphylococcus aurous, further it can be employed as an antimicrobial agent for prohibiting implant linked infections.

Automated summary

Zinc sulfide nanoparticles were prepared successfully using sol-gel precipitation method, with structural analysis confirming cubic formation. The nanoparticles showed antibacterial properties against Escherichia coli and Staphylococcus aureus, suggesting potential as an antimicrobial agent for preventing implant-linked infections.
