چکیده
Green synthesis of nanoparticles has received great attention from scientists due to their undeniable applications in all field of science. In this study, an eco-friendly and fast approach is reported for the preparation of silver nanoparticle (Ag NPs) using Spartium junceum flower extract, as a reductant and stabilizer agent, from aqueous solution of silver nitrate. The biosynthesis of silver nanoparticles was optimized by investigating the reaction parameters including: pH, temperature, concentration of plant extract and interaction time. The silver nanoparticles were characterized by UV-vis, fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), dynamic light scattering (DLS) and transmission electron microscopy (TEM) analyses. Also, the biosynthesis of Ag NPs was confirmed by UV-vis spectroscopy through the presence of a characteristic surface plasmon resonance (SPR) band for Ag NPs at lmax=420 nm. The synthesized nanoparticles were crystalline in nature, nearly spherical in shape with 15-25 nm range of sizes.کلیدواژه ها
