Neem Extract-Mediated La (III) and Ce (IV) Oxide Nanoparticles Probing for Their Dielectric and Biological Applications

This work represents a green synthesis of Lanthanum and Cerium oxide nanoparticles (NPs) using Azadirachta Indica (Neem) leaf extract. La۲O۳ and CeO۲ NPs were characterized for purity and structural properties using different techniques such as Ultra Violet-Visible (UV-Visible), Fourier Transform Infra-Red (FT-IR), X-ray Diffraction (XRD) and Brunauer–Emmett–Teller (BET) analysis. Scanning Electron Microscopy (SEM) and High-Resolution Transmission Electron Microscopy (HRTEM) reveal a spherical shape having an average size of ۱۰-۵۰ nm. BET analysis shows an increment of surface area from ۱۴.۹۰۹ m۲/g to ۴۲.۱۴۴ m۲/g. The peak pore volume of metal oxide nanoparticles increases from ۰.۱۸۱ cm۳/g to ۰.۲۳۳۸ cm۳/g. Further, synthesized NPs were analyzed for dielectric behavior, antibacterial studies, and hemolysis assay.
