摘要：The electromagnetic (EM) enhancement in shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) was systematically analyzed for the first time by using 3D-FDTD. Compared with a bare metallic nanoparticle directly contact to a gold flat surface, a hot spot with stronger EM enhancement occurs in the junction between silica shell-isolated nanoparticle and flat surface in SHINERS. The largest enhancement factors can be as high as 9 orders of magnitude. The exact locations of hot spots and their EM enhancement strongly depend on the thickness of the silica shell.
