Visible Light-Assisted Soft-Chemistry Route to Silver Nanomaterials at Room Temperature

Abstract

Silver nanoparticles (AgNPs) were synthesizd by a light-assisted liquid phase reduction method with sodium hypophosphite as a reducing agent. DTAB was used to perform as the surfactant. AgNPs were characterized with powder X-ray diffraction (XRD) and scanning electron microscope (SEM). The result showed that the nanoparticles are spherical and cube. The effect of temperature on the morphology and properties of silver nanoparticles was investigated. The ultraviolet-visible (UV-vis) absorption and the fluorescent properties of the as-prepared AgNPs were explored.
