We have synthesized silver nanoparticles using silver nitrate and Azadirachta indica (Neem) aqueous leaf extract at
room temperature. The method used for synthesis is simple, rapid, environmental free and do not involve toxic chemicals. The
terpenoids and flavonoids available in neem plant leaf extract act as both capping and reducing agents. The synthesized
nanoparticles are characterized UV Visible spectroscopy, X ray diffraction analysis and fluorescence spectroscopy.
