摘要

Sesbania sesban extract solution (SSL) was used as a reducing and stabilizing agent for the synthesis of colloidal silver nanoparticles (AgNPs). The effect of time on the formation of nanoparticles was investigated using ultraviolet-visible spectroscopy. The AgNPs were synthesized after 25 min and characterized by high-resolution transmission electron microscopy, scanning electron microscopy (SEM) and X-ray diffraction (XRD). The average sizes of nanoparticles were estimated to be between 10 and 30 nm. The XRD of AgNPs, after 4 months, showed the stability of nanoparticles in air. The effects of silver nitrate concentrations and SSL concentrations on the morphology and size of synthesized AgNPs were observed by SEM.
