Metal hollow nano-structures have been widely investigated and applied for high sensitive SERS sensing by using the generated regular hot spots from the coupling effect between the nanoparticles.Recently, mutipole plasmonic mode resonances in metal nanoshell structure,such as dipole, quadrupole, and sextupole modes, have been theoretically investigated by researchers with the aim for potential applications in bio-sensing, SPASER lasers, or nonlinear nano-photonics.Here, in this work, multi-pole plasmon resonance has been characterized in the self-assembled metal hollow-nanosphere (HNS) arrays,which has been demonstrated to be an ideal SERS substrate with the merit of hot spots generated by the interparticle coupling effect between HNSs.
