← ScienceWhich mechanism limits the energy transfer efficiency between two quantum dots with mismatched energy levels in adjacent orbitals?
A)Increased vibrational relaxation
B)Decreased Förster resonance energy transfer✓
C)Enhanced Auger recombination
D)Increased surface trapping of excitons
💡 Explanation
When energy levels are mismatched, Förster resonance energy transfer (FRET) efficiency decreases because the spectral overlap between donor emission and acceptor absorption is reduced, limiting the nonradiative dipole-dipole energy transfer. Therefore decreased FRET results, rather than increased vibrational relaxation, Auger recombination or surface trapping, which require different defect mechanisms.
