Optical, structural and XPS studies of Ag nanoparticles prepared via Melia azedarach plant extract

摘要

In the present study, Ag nanoparticles were synthesized by using leaves extract of plant Melia azedarach. Green method was followed in the synthesis of Ag nanoparticles. By this method, Ag nanoparticles have been synthesized in the size range 19 nm-28 nm with maximum absorbance at 325 nm of wavelength. The prepared Ag nanoparticles were found to exhibit fcc structure. Morphological study of the Ag nanoparticles was carried out through FESEM and TEM. FTIR and XPS investigations of prepared nanoparticles revealed the presence of plant components in the prepared nanoparticles and the chemical state of elements present in the synthesized nanoparticles, respectively. Antibacterial activity of Ag nanoparticles was also investigated against pathogens, Escherichia coli and Staphylococcus aureus.
