“…The enhancement of the local electric field is due to the fact that the optical cross-section of the gold and silver subwavelength particles is many times larger than the geometric scattering cross-section [181]. The interaction of the plasmons with the fluorescent substance can improve the luminescence rate of the material [182], reduce the fluorescence lifetime [183], and improve the light stability of the luminescent material [184].…”

Abstract:The interaction of exciton-plasmon coupling and the conversion of exciton-plasmon-photon have been widely investigated experimentally and theoretically. In this review, we introduce the exciton-plasmon interaction from basic principle to applications. There are two kinds of exciton-plasmon coupling, which demonstrate different optical properties. The strong exciton-plasmon coupling results in two new mixed states of light and matter separated energetically by a Rabi splitting that exhibits a characteristic anticrossing behavior of the exciton-LSP energy tuning. Compared to strong coupling, such as surface-enhanced Raman scattering, surface plasmon (SP)-enhanced absorption, enhanced fluorescence, or fluorescence quenching, there is no perturbation between wave functions; the interaction here is called the weak coupling. SP resonance (SPR) arises from the collective oscillation induced by the electromagnetic field of light and can be used for investigating the interaction between light and matter beyond the diffraction limit. The study on the interaction between SPR and exaction has drawn wide attention since its discovery not only due to its contribution in deepening and broadening the understanding of SPR but also its contribution to its application in light-emitting diodes, solar cells, low threshold laser, biomedical detection, quantum information processing, and so on.

“…Although many theoretical discussions have been reported on this subject in recent years, 4,8,11,12 so far they either adopted a too simplified an isotropic model that is essentially scalar, 11 or treated spontaneous emission classically, 12 or adopted phenomenological models. 4,8 In highly inhomogeneous media like 3D photonic crystals, electromagnetic ͑EM͒ fields are also highly inhomogeneous, therefore, we have to consider photon-atom coupling in a full vectorial way.…”

“…[1][2][3][4][5][6][7][8][9] Martorell and Lawandy reported the first observation of inhibited spontaneous emission ͑SE͒ of dye molecules in dilute colloidal crystals composed of polystyrene microspheres in water. 4 They found a single exponential decay of the excited state and a variation of the fluorescence lifetime of 1.75 times. However, Tong et al argued that this remarkable variation was caused mainly by electronic and chemical interactions between dye molecules and the medium, instead of a pure PBG effect.…”

“…1 In the last decade, there appeared great interest in controlling the spontaneous emission rate via threedimensional ͑3D͒ photonic crystals, [2][3][4][5][6][7][8][9][10][11][12] which are artificial periodic materials. It was suggested that if the atomic transition frequency lies inside the photonic band gap ͑PBG͒, the spontaneous emission will be completely inhibited, 2 as there is no photon mode that can perturb atomic states.…”

Weak photonic band gap effect on the fluorescence lifetime in three-dimensional colloidal photonic crystals

The photonic band gap ͑PBG͒ effect on the fluorescence lifetime of molecules in three-dimensional colloidal photonic crystals is studied theoretically by means of a full vectorial quantum electrodynamics. In these colloidal systems where the refractive index contrast is as low as below 1.2, the PBG-induced lifetime variation is found to be below 5%. Our theoretical simulations can help to distinguish the pure PBG effect on the observed fluorescence lifetime variation from other effects such as complex electronic and chemical interactions that can occur in condensed-matter materials.
