We study the surface enhanced Raman scattering (SERS) from bimetallic core-shell nanoparticles by taking into account the nonlocal effect. The Gersten-Nitzan model is applied to investigate SERS from a molecule adsorbed on the nonlocal bimetallic nanoparticle. Numerical results show that there are two enhanced SERS peaks for bimetallic coated nanoparticles, and nonlocal effects will lead to less enhancement and blue-shift of SERS peaks. In addition, unusual resonant electric-field patterns are found in the nonlocal gold core in comparison with those in the local case. Our investigation is helpful for understanding some details of SERS schemes in nano-optics and plasmonics when nonlocal effects are considered.
