Abstract: (1357 Views)
In this study, first the magnetite nanoparticles encapsulated by silica were synthesized by one-pot co-precipitation method. These Magnetite/silica nanoparticles were then covered by a silver shell through chemical reduction with different reduced time durations. Structures were characterized with XRD and FT-IR, which confirmed the formation of magnetite/silica/silver nanoparticles. In order to study the optical properties of samples, were evaluated their absorbance spectra in UV-Vis domain. The results showed that by increasing silver shell thickness, the absorption pic, related to surface plasmon resonance, shift to short wavelength and its amplitude increases.
