Abstract
Zinc Oxide and Magnesium doped ZnO Nanoparticles (Mg-ZnO NPs) have been synthesized by chemical co-precipitation method and their structural, optical, thermal properties and antibacterial activity have been studied. XRD spectra revealed that all synthesized NPs are hexagonal wurtzite structure and the size of ZnO and Mg-ZnO NPs is 51 and 42 nm. FTIR spectra of ZnO and Mg-ZnO NPs have the peak at 463 and 470 cm-1 . Mg-ZnO NPs have enhanced the thermal stability region from (177 - 288 oC) to (198 - 296 oC). ZnO NPs have high antibacterial activity against Escherichia coli while Mg-ZnO NPs has the Pseudomonas aeroginosa
