Preparation, characterization, and antibacterial activity of Ni, Sn co-doped ZnO nanoparticles: Effect of Sn doping concentration

Ni, Sn co-doped ZnO nanoparticles have been prepared by chemical method at room temperature. The effects of Sn on the structural, morphological, optical, electrical, and anti-microbial properties of the prepared nanoparticles have been evaluated and discussed. The crystallite size and the unit cell properties have been influenced by the doping concentration of Sn. The addition of Sn enhances the texture coefficient of the nanoparticles. The optical band gap of the material is blue-shifted as the doping concentration of Sn increases. The prepared nanoparticles have high hole concentration than electron concentration. The nanoparticles became more transparent at high doping concentrations. The effect of Sn concentration against E. coli, S. aureus, and P. aeruginosa has been evaluated.
