Surface-enhanced Raman scattering of C60 on co-modified substrate of Fe3O4 and Au nanoparticles

By introducing Fe3O4 magnetic nanoparticles, the Fe3O4 and Au nanoparticles co-modified substrate shows high SERS activity which is superior to bare Au nanoparticles modified substrate. High-quality SERS spectrum of C60 can be obtained on it. Experimental results indicate that the co-modified substrate is very effective and active.
