Dynamic and stationary characteristics of nonlinear luminescence in molecular layers with electronic-excitation energy transfer

Abstract

We carry out an analysis of the characteristics of nonlinear luminescence of a multicomponent layer system consisting of layers of molecules of a sensitizer, donor, and acceptor with inductive-resonance transfer of energy between the components of the molecular ensemble. We show that in a stationary regime bistable dependences of the populations of excited states of molecules on excitation intensity are realized without external feedback. For pulse pumping, we show the possibility for forming response-luminescence pulses with widely variable characteristics: shape, duration, intensity, and delay.
