Structural, Morphological and Antimicrobial Activity of pure and Aluminum doped Zinc Sulfide Nanoparticles

Abstract

Undoped and Aluminum (Al) doped Zinc Sulphide (ZnS) Nanoparticles (NPs) has been prepared by chemical co- precipitation method using plant zinc sulphate, Aluminum sulphate and Thiourea . The X-Ray Powder Diffraction (XRD) studies reveals Cubic structure for undoped and Aluminum doped ZnS NPs. Scanning Electron Microscopy (SEM) images shows formation of smooth surfaced ZnS NPs  and average particles size was found in the range of 17 nm from the result the Aluminum doped ZnS were influenced to increase ZnS NPs particle size.  The disk diffusion method was used to screen the antimicrobial activity of Aluminum doped ZnS NPs against different gram positive, gram negative bacterial and fungus culture from this investigation Aluminum doped ZnS NPs  have potential antimicrobial agent which was show excellent zone of inhibition (ZoI)  at different concentration against all tested microorganisms.
