摘 要：(Ag + Fe)-doped ZnO nanopowders have been synthesized using combustion method.Ag doping level was kept as 2 at.%,and Fe doping level was varied from 3 to 6 at.%,and the structural,optical,surface morphological,and antibacterial properties have been investigated.The structural studies show that ZnO/（Ag + Fe） nanopowders have hexagonal wurtzite structure with a preferential orientation along the（101） plane.The FE-SEM images indicate that there is a gradual decrease in the grain size with the increase in the doping level of Fe,and the TEM images are correlated well with FE-SEM images.The XPS profile clearly confirms the presence of expected elemental composition.Photoluminescence studies reveal the presence of extrinsic defects in the material.Antibacterial activity of Ag- and Fe-doped ZnO nanopowders against Vibrio parahaemolyticus,Vibrio Cholerae,and Staphylococcus aureus bacteria was also investigated.
