Silver nanoparticles were synthesis in aqueous solution with NaBH4 and in alcoholic solution with CH3OH . In order to keep the silver particles in the nanometer range , polyvinylpyrrolidone (PVP) was used . The alcohol served both as solvent and reducing agent for silver ions and cause of slow reaction rate . The synthesis was carried out by microwave .The results were confirmed with TEM images and UV-Vis spectrum.
