To further improve the generality of molecules and SERS substrates,we have employed a strategy of "borrowing SERS activity" that is to coat Au nanoparticles with ultra-thin film of various transition metals to form core-shell nanoparticles,such as Au@Pd,Au@Pt,Au@Ni,Au@Co.

Through the investigation of surface enhanced Raman scattering(SERS) spectrum by p-hydroxybenzoic acid(PHBA) used as a probe molecule,it is found that the silver nanostructure is a highly efficient SERS active substrate whose SERS effect is even superior to the commonly.
