← ScienceWhich risk increases when manipulating electron configurations in quantum dot LED materials?
A)Increased triplet-triplet annihilation probability✓
B)Enhanced Dexter energy transfer efficiency
C)Augmented Förster resonance energy transfer
D)Suppressed intersystem crossing efficacy
💡 Explanation
Increased manipulation focusing on confined quantum dots creates more excitons; triplet-triplet annihilation then increases because of higher exciton density and efficient interaction due to Förster resonance energy transfer, therefore the probability is higher, rather than the other options, under limited energy transfer.
