Abstract

In this study, silver nanoparticles have been synthesized using green synthesis from Echium amoenum Fisch. &C.A.Mey. extract. The extract of this flower was used to reduction of silver nitrate solution and stabilization of formed silver nanoparticles. The extract of this flower contains different anthocyanin compounds, polyphenols, and vegetable stearic fatty acids that can contribute in reduction and stabilization of silver nanoparticles. Characterization of the nanoparticles was performed using X-ray diffraction method (XRD), dynamic light scattering (DLS), UV–Visible spectrum, and open aperture Z-scan method. The measurements showed that stable nanoparticles with an average size of about 54 nm were synthesized and the use of this extract was successful. Adding a few droplets of the extract to the nano-colloid made the peak of localized surface plasmon resonance (LSPR) clearer. Also, the trend of absorption spectrum changes with the addition of droplets and their nonlinear absorption changes were investigated. Nonlinear optical measurements also showed that silver nanoparticles synthesized by this method exhibit reversed saturation absorption which is due to multi-photon absorption and electrostriction effects. This green synthesis method can lead to the synthesis of stable and high-performance silver nanoparticles with high potential in electro-optic devices and can be considered as an environmentally friendly and low-cost synthesize method.
