摘要：

The work reported for the first time in this article describes the kinetic study of silver nanoparticles formation using Phyllanthus emblica amla extract. The synthesized silver particles exhibit an intense surface plasmon resonance band in the visible region at 455 nm. The variation in concentrations of amla extract, Ag+ ions, cetyltrimethyl ammonium bromide (CTABr), and reaction time play crucial roles for nucleus formation and the growth processes. The Ag+ ions reduction into metallic Ag-0 is due to the presence of polyphenolic groups in the amla extract and thereafter, their agglomeration into nanoparticles. Due to the formation of spherical Agnanoparticles there is a appearance of a sharp surface plasmon resonance band in the UV-visible region. Silver nanoparticles (AgNPs) were characterized by TEM, XRD and FTIR techniques. (C) 2021 Elsevier B.V. All rights reserved.
