摘要

The present study explores that the aqueous extract of the seeds of Nyctanthes arbor-tristis (aka night jasmine) is very efficient for the synthesis of stable AgNPs from aqueous solution of AgNO3. The extract acts as both reducing (from Ag+ to Ag0) and capping agent in the aqueous phase. The constituents in extract are mainly biomolecules like carbohydrates and phenolic compounds, which are responsible for the preparation of stable AgNPs within 20?min of reaction time at 25?°C using without any severe conditions. The synthesized silver nanoparticles were characterized with UV–Visible spectroscopy, FT-IR, XRD and SEM. UV–Vis spectroscopy analysis showed peak at 420?nm, which corresponds to the surface plasmon resonance of AgNPs. XRD results showed peaks at (111), (200), (220), which confirmed the presence of AgNPs with face-centered cubic structure. The uniform spherical nature of the AgNPs and size (between 50 and 80?nm) were further confirmed by SEM analysis.
