Electronic excitation energy transfer is studied theoretically within a prototype system of quantum dots using the excitonic representation of the electronic states of two quasi-zero dimensional subsystems, between which the excitation energy is transferred in a process treated as an irreversible kinetic phenomenon. The electron-phonon interaction is used to circumvent the energy conservation problem, especially when considering the uphill and downhill excitation transfer processes. The theory is studied upon utilizing a simplified model of two interacting quantum dots, both coupled to their environment. The theoretical approach is documented by numerical calculations. The results could be relevant to various cases of the electronic excitation energy transfer between quasi zero dimensional nanostructures.
