Molecular J-aggregates are widely used as emitters to achieve the quantum effects, such as the strong coupling phenomenon. We investigate the lateral shift splitting/Goos–Hänchen (GH) shift splitting induced by strong coupling in Kretschmann configuration involving molecular J-aggregates by using classical methods. The optical response of molecular J-aggregates is modeled by a single Lorentzian oscillator, and Fresnel equations and the stationary phase method are employed to solve our proposed structure. Our results show that the lateral shift versus the incident wavelength shows Rabi splitting-like line shape and the reflection spectrum exhibits the strong coupling phenomenon. Based on the results of the previous experiment work, we well explain the relation between Rabi splitting and the thickness of the metal film and provide a new method to choose the parameters of the structure for experiment.

Partial Destruction

Palladium and silver nanoparticles are formed on the surface of tubular J-aggregates of an amphiphilic tetrachlorobenzimidacarbocyanine dye by reduction of the respective metal cations in aqueous solution. Upon addition of the palladium complex Na2PdCl4to the aggregate solution, the absorption spectrum shows significant changes which is explained by partial destruction of the aggregates. Cryogenic transmission electron microscopy (cryo-TEM) images show that the tubular J-aggregates are randomly covered by well-separated Pd nanoparticles of approximately 1–3 nm size. Larger particles and higher particle density along the aggregates are obtained when an auxiliary reducing agent is added to the solution. The presence of the metallic particles leads to efficient fluorescence quenching giving clear evidence for super quenching. In similar experiments using AgNO3, silver nanoparticles are grown which are larger in size but less dense distributed along the aggregates. At least in the case of the silver particles, the spontaneous formation of metal nanoparticles is assumed to be initiated by a photo-induced electron transfer process (PET).
