ABSTRACT = {Pure zinc sulfide nanoparticles and doped with silver (0.5,1,1.5,2.5, and 3.5) % wt. were 
prepared by green method. The structural properties were studied using X-ray diffraction 
technology(XRD). The diffraction patterns showed the particles were crystalline and had a 
zinc-blend structure with different average grain size. The surface topography was 
investigated by Scanning Electron Microscope (FE-SEM), it was found the shape is 
spherical and had different nanosized. Chemical purity was studied using Energy Dispersive 
X-ray Spectroscopy(EDX), the results showed the appearance of basic elements (Zn, S) and 
silver. The results of Fourier Transform Infrared Spectroscopy(FTIR) showed functional 
groups belonging to ascorbic acid, zinc, and sulfur. The topography and surface roughness 
were studied using an Atomic Force Microscope, it was found the particles have spherical 
shapes, roughness values, and various average grain sizes. The optical properties were 
studied using ultraviolet -visible light spectroscopy (UV-Vis), where the absorption 
spectrum showed strong distortions towards the ultraviolet region and a large value of 
optical energy gap compared with raw material.},
