▎ 摘　　要

The deposition of silver nanoparticles on graphene, induced additional corrugations of graphene, a new type of artificial defects. It is very notable that new significant Raman modes were achieved and rationally assigned, indicating that SERS effect is a powerful technique not only for identifying the number of graphene layers but for investigating the interaction mechanism of graphene and nanoparticles. This is of crucial importance for developing the graphene-based electronic devices modified by atomic-clusters or nanoparticles.
