Popis: The effect of a two-dimensional quantum-confined structure formed at a polymer/polymer interface on the radiative recombination of excitons (i.e., electroluminescence) is investigated. It is shown that the implementation of such a structure in a polymer film leads to an increase in the emission intensity by more than two orders of magnitude and a twofold decrease in the voltage threshold for double injection. It is established that the polymer/polymer interface serves as the front of exciton recombination, and its position inside the film affects the electroluminescence intensity. The position of the two-dimensional structure within the polymer film corresponding to the highest intensity of radiative recombination is a function of the ratio of electron and hole mobilities.
