Excitation Transport by the Resonant Dipole-Dipole Interaction in a Closely Packed Quantum-Dot Film

We present a theoretical analysis of the optical properties of quantum-dot aggregates with diag- onal and o-diagonal disorder. Dot-to-dot exciton energy transport by the resonant dipole-dipole interaction is dealt with in the system of semiconductor nanocrystals embedded in a conjugated polymer matrix .lm. In order to investigate the absorption spectrum of the aggregates and excitation transport among quantum dots, we consider both the diagonal disorder due to dot size disparity and the o-diagonal disorder due to conformational and inter-dot-distance randomness.c KCI Citation Count: 2
