Abstract

A quantum theory for the light absorption and photoluminescence of a molecule (luminophore) interacting with a J-aggregate linear molecular chain is constructed. It is shown that together with the band states of Frenkel excitons in the molecular chain the contribution to light absorption and luminescence comes from local levels that split off from the exciton band as a result of the interaction between the molecular chain and the luminophore. It is also demonstrated that the contribution to light absorption and photoluminescence from local levels is non-linearly dependent on the coupling parameter between the luminophore and the J-aggregate molecular chain.
