英文摘要Coupled plasmonic modes of noble metal nanoparticles are of interest in fields spanning chemistry, physics, materials science, and biology. We systematically investigated the dipole-multipole (D-M) coupling in asymmetric dimers of Au NRs through electromagnetic simulations. First, we calculated the hybridization between Au NR multipole and Au NR dipole in terms of far-field resonances, near-field profiles, and angular scattered radiation profiles at different arrangements. Notably, we found that the parallel aligned D-M plasmonic hybridization leads to asymmetric split resonances that include a multipolar resonance-dominated mode of higher energy and a dipolar resonancedominated mode of lower energy. Then, we evaluated the "gap space effect" on the strength of D-M hybridization. Furthermore, we studied the dipole's influence on the D-M coupling via systematically evaluating the optical properties of the dipolar rod's effects on the hybridized system. Importantly, we discussed the carrier concentration and the damping velocity's effect on each mode in terms of spectral shifts and near-field enhancement factors, and we found that dipole-octapole (DO) hybridization shows stronger interactions compared to dipole-quadrupole (DQ) hybridization. We hope our work may boost the fundamental understanding of the D-M plasmonic hybridization system and facilitate plasmonic-photonic innovations and nanoplasmonic applications, such as fluorescence imaging, energy storage, biosensors, metamaterials, etc.
