“…FRET is a very efficient exciton energy transfer mechanism via a resonant, near-field, dipole-dipole interaction [11,12,13,14,15]. It is commonly observed in biological systems, conjugated polymers, wires, dots [11,12,13,14,15], where it dominates at short and intermediate distances (0.5-10nm) [11,12,13,14,15].…”
