The optical characteristics of Au, Ag, and AgcoreAushell nanoparticles with dopamine concentrations

In this work, Au, Ag and Ag
_core
Au
_shell
nanoparticles have been prepared by citrate reduction method and their optical properties with different concentration of dopamine were compared. The result shows that the absorption and Raman scattering spectra of Au, Ag and Ag
_core
Au
_shell
nanoparticles are strongly dependent on the dopamine concentrations.
