| 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.
