摘要: Abstract We study polyvinyl pyrrolidone (PVP) stabilization of aqueous phase silver nanoparticles (AgNPs) sols. Glucose is used as the reducing agent. Addition increasing amounts NaOH cause interesting variations in sol pH and localized surface plasmon resonance (LSPR) behavior. The LSPR information coupled with small angle X-ray scattering (SAXS) analysis TEM imaging to delineate various nanoparticle characteristics. Both fractal aggregate nanostructures anisotropic objects are found form under different conditions.
