Phytosynthetic Fabrication of Lanthanum Ion-Doped Nickel Oxide Nanoparticles Using Sesbania grandiflora Leaf Extract and Their Anti-Microbial Properties

Over the past few years, photogenic fabrication of metal oxide nanoparticles has attracted considerable attention, owing to simple, eco-friendly, and non-toxic procedure. Herein, we fabricated NiO altered their optical properties by doping with a rare earth element (lanthanum) using Sesbania grandiflora broth for antibacterial applications. The lanthanum was systematically studied. prepared nanomaterials were investigated through UV-Vis diffuse reflectance spectra (UV-DRS) analysis, structures studied X-ray diffraction analysis. morphological features examined scanning electron microscopy transmission microscopy, elemental structure analyzed energy-dispersive spectral oxidation states photoelectron spectroscopy. Furthermore, action La-doped zone inhibition method Gram-negative Gram-positive bacterial strains such as Escherichia coli Bacillus sublitis. It evident from obtained results that optimized compound NiOLa-04 performed better than other compounds. To best our knowledge, this is first report on phytosynthetic rare-earth ion Lanthanum (La3+)-doped Nickel Oxide (NiO) anti-microbial studies.
