Abstract

The present study reports the green synthesis of silver nanoparticles using Mimosa pudica as reducing agent. The formation of silver nanoparticles was confirmed by UV-Vis absorption spectroscopy and Transmission Electron Microscopy. The average particle size of the synthesised material is about 16 nm and are almost spherical in shape. Nonlinear optical absorption properties of synthesized “Green” AgNP-PVA were investigated using open-aperture Z-scan technique at 532 nm and it can be used to study the optical limiting property. The adopted green-synthetic approach is very much cost-effective..
