SYNTHESIS OF SILVER NANOPARTICLES BY EXTRACT OF NEEM (AZADIRACHTA), TULSI(OCIMUM TENUIFLORUM) AND MINT(MENTHA) LEAVES USING GREEN SYNTHESIS METHOD

Abstract

There are several possible uses of silver nanoparticles (AgNPs) in energy storage systems, antimicrobial sensors, and other biological sensors. Silver nanoparticles were synthesized using extract obtained from leaves of Azadirachta Indica (Neem), Ocimum Tenuiflorum (Tulsi), and Mentha (Mint). Thin films of various samples were then prepared using drop-cast method. In order to study their structural properties, they are then characterized with different analytic techniques like X-ray diffractometer (XRD) and ultraviolet visible Spectroscopy. To compare the particle size of NPs obtained from different plant leaves, XRD characterization was done. XRD patterns ratifies synthesis of silver nanoparticles in single crystalline phase and confirms the FCC structure with a particles size of 13.58 nm (obtained from neem extract). UV-Visible absorption spectrum for different samples neem, tulsi and mint were recorded in the wavelength ranges of (270-600) nm.
