چکیده
|
The sol-gel method is successfully used for the synthesis of zno nanoparticlesdoped with di erent concentrations of mg. the structure, morphology, chemical composition,optical and antibacterial activity of the nanoparticles were studied as a function ofthe mg doping concentration. the synthesized zno samples show a hexagonal wurtzitestructure, and the phase segregation takes place for the 15% amount of doping. tem imagesverify the formation of nanoparticles in the range of 30-55 nm. ftir and eds results alsoconrm the successful incorporation of mg in the zno structure. optical investigationindicates an increase in band gap energy with an increase in doping content. theantibacterial activities of the nanosuspensions were tested against escherichia coli (gramnegative) and streptococcus mutans (gram-positive) cultures. zno:mg nanosuspensionshows high antibacterial activity, which slightly decreases with the amount of mg
