In this study, synthesis, characterization and antimicrobial properties of pure and Mn-doped ZnO nanoparticles have been investigated. Undoped and Mn-doped ZnO nanoparticles were prepared by using Co-precipitation method. The synthesized Mn-doped ZnO nanoparticles were characterized by XRD, SEM, EDX, and UV-Vis spectroscopy was used to measure the band gap energy. The antimicrobial activity of Mn-doped ZnO nanoparticles was carried out by using agar diffusion method.
Formation of nanoparticles was confirmed by XRD technique. XRD analysis showed hexagonal wurtzite structure of Mn doped and undoped ZnO nanoparticles. The average grain size for undoped ZnO nanoparticles was 16.72nm, and the size of Mn-doped ZnO nanoparticles was 6.14nm synthesized by co-precipitation method with different chemicals.
