| Abstract: | Low-symmetry SiO2/Ag core-shell composite nanostructures have been prepared by simply carrying out the silver mirror reaction on the top of the self-assembled monolayer arrays of SiO2 nanoparticles.The surface morphologies and optical properties of the core-shell composite nanostructures were characterized by TEM,SEM and UV-Vis spectroscopy.The surface-enhanced Raman scattering(SERS) activities of the core-shell composite nanostructures were investigated with methylene blue as a probemolecule. |
