Plasmon-Frenkel-exciton in a clustered solid
نویسندگان
چکیده
The standard theory of the Frenkel exciton (a small radius exciton) is applied to a fullerene 2D solid. It is the dipole collective electron excitation of a single cluster which forms the delocalized plasmon-Frenkel-exciton (PFE) in a crystal. The PFE retarded interaction is taken into account. We present transverse PFE-polariton dispersion curves along with the Coulomb problem solution for longitudinal excitation in the 2D plane. c © 1998 Elsevier Science B.V.

Excitons and Radiation Damage in Alkali Halides
The quantum mechanical description of atomic spectra was the beginning of a new era of quantum physics which today is the theoretical basis of nuclear and solid state physics, chemistry, and biochemistry [1,2]. Quantum mechanics opened also a new look to solid state physics which will be illustrated by the development of the conception of excitons [3]. One of the basic quantum mechanical proble...
متن کاملExciton dispersion in molecular solids.
The investigation of the exciton dispersion (i.e. the exciton energy dependence as a function of the momentum carried by the electron-hole pair) is a powerful approach to identify the exciton character, ranging from the strongly localised Frenkel to the delocalised Wannier-Mott limiting cases. We illustrate this possibility at the example of four prototypical molecular solids (picene, pentacene...
متن کاملObservation of selective plasmon-exciton coupling in nonradiative energy transfer: donor-selective versus acceptor-selective plexcitons.
We report selectively plasmon-mediated nonradiative energy transfer between quantum dot (QD) emitters interacting with each other via Förster-type resonance energy transfer (FRET) under controlled plasmon coupling either to only the donor QDs (i.e., donor-selective) or to only the acceptor QDs (i.e., acceptor-selective). Using layer-by-layer assembled colloidal QD nanocrystal solids with metal ...
متن کاملNonlinear resonance reflection from and transmission through a dense glassy system built up of oriented linear Frenkel chains: Two-level model
A theoretical study of the resonance optical response of assemblies of oriented short (as compared to an optical wavelength) linear Frenkel chains is carried out. Despite the fact that the energy spectrum of a single chain is composed of the bands of Frenkel exciton states, a two-level model is used to describe the optical response of a single linear chain. We account for only the (on-resonance...
متن کاملStrong Exciton-Plasmon Coupling in MoS2 Coupled with Plasmonic Lattice.
We demonstrate strong exciton-plasmon coupling in silver nanodisk arrays integrated with monolayer MoS2 via angle-resolved reflectance microscopy spectra of the coupled system. Strong exciton-plasmon coupling is observed with the exciton-plasmon coupling strength up to 58 meV at 77 K, which also survives at room temperature. The strong coupling involves three types of resonances: MoS2 excitons,...
