The silver nanoparticles (Ag NPs) show a very interesting optical property of surface plasmon resonance in the visible region due to which they find application in photovoltaics for enhancing the efficiency of solar cells. For this the synthesized Ag NPs need to be stable and pure. The present work reports the green synthesize Ag NPs from an extract of Azadirachta Indica (Neem) leaves as reducing/stabilizing and capping agent. The morphology and stability of the biosynthesised Ag NPs were investigated by SEM, FTIR and UV-Visible spectroscopy. The SEM images confirmed the formation of spherical silver nanoparticles uniformly distributed throughout the solution. Visual perception confirmed the formation of the Ag NPs after the addition of the leaf extract the same was confirmed using the UV-Vis spectroscopy absorption peak at 420- 430 nm. The FTIR spectroscopy confirmed the functional groups responsible for the bioreduction of Ag+ to Ag NPs. The synthesised Ag NPs were stable for a long period of time.
