title: Multiple coupling in plasmonic metal/dielectric hollow nanocavity arrays for highly sensitive detection.
abstract: Recently, the plasmonic coupled optical cavity has gained much attention due to its attractive properties in light manipulation, e.g. high Q optical resonance, local field enhancements and extraordinary transmission. The strongly enhanced local field originated from the plasmonic resonance hybridizing with the optical cavity mode presents great potential for application to chemical and biological sensing. Here, the multiple coupling effect between plasmonic mode and optical cavity mode has been demonstrated in self-assembled metal/dielectric hollow-nanosphere (HNS) arrays and the strongly enhanced local field originated from the inter-coupling of the plasmonic cavities was further employed for highly sensitive recyclable SERS sensing.
