Implication
Comprehensive review reveals fundamental optical coupling phenomena in adjacent metallic nanoparticles, highlighting mechanisms for intense near-field electromagnetic hotspots.
Key Points
- To review the theoretical mechanisms and experimental developments governing optical plasmon interactions in strongly coupled metallic nanostructures.
- Synthesized theoretical models including plasmon hybridization and classical electrodynamics across coupled metallic architectures.
- Evaluated optical spectroscopy methods measuring localized surface plasmon resonances in nanostructures with sub-nanometer interparticle gaps.
- Strong capacitive and electromagnetic interactions between metallic nanoparticles induce dramatic spectral shifts and create localized electromagnetic hotspots.
- Plasmon hybridization models accurately capture the complex multipolar interactions that emerge as interparticle spacing decreases to near-contact regimes.
