Abstract
This 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).
