dc.description.abstractThis article gives some proposals on how to grow silver nanoparticles using different methods. Dilute silver salts are recommended as the metal precursor starting solutions. The formation of the silver nanoparticles is to be monitored using UV-Vis absorption spectroscopy so as to reveal the formation of silver nanoparticles and how they will exhibit surface plasmon absorption maxima at 418 - 420 nm from the UV–Vis spectrum. The Mie light scattering theory will be applied and the experimental results analyzed to show the diameter of silver nanoparticles in colloidal solution. Energy-dispersive spectroscopy (EDX), X-ray diffraction (XRD), transmission electron microscopy (TEM) and UV–Vis spectroscopy are proposed to be used to characterize the formed silver nanoparticles obtained. The energy-dispersive spectroscopy (EDX) of the nanoparticles dispersion will confirm the presence or absence of elemental silver signal peaks. The size and morphology of the formed silver nanoparticles will be determined by transmission electron microscopy. The synthesized silver nanoparticles will be structurally characterized by using X-ray diffraction and transmission high-energy electron diffraction (HEED) and the peaks in the XRD pattern will be compared to the standard values of the face-centered- cubic form of metallic silver (ICCD-JCPDS card no. 4-0787).
