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 °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.

硫化锌（ZnS）纳米粒子已通过溶胶-凝胶沉淀法成功制备。XRD分析可确保成功形成立方结构，并使用Debye Scherrer方程确定微晶尺寸，发现200℃退火的ZnS样品的微晶尺寸为36 nm。使用HRSEM和HRTEM研究了表面形态，并且从SAED图案获得了样品的晶格参数，发现其与从XRD图案获得的值非常相似。EDS研究证实了ZnS纳米粒子的进一步元素映射。进一步使用Kubelka Munk函数估计带隙值，该值在3.58至3.64 eV之内。进一步研究了ZnS的抗菌活性，发现它是大肠杆菌和金黄色葡萄球菌的抗菌剂，
