We use Au@SiO₂ nanoparticles(NPs) to systematically and comprehensively study the relationship between nanostructure and activity for surface-enhanced Raman scattering. Calculation simulation using the finite different time domain method verifies the experiment results and further reveals that the particle size and the distance between the NPs play vital roles in the surface-enhanced Raman scattering(SERS). Furthermore, in order to better simulate the real experiment, a Au@SiO₂
