← ScienceWhich outcome occurs when a quantum dot's passivating shell is decreased in thickness?
A)Increased probability of electron tunneling✓
B)Reduced quantum confinement effect
C)Enhanced Förster resonance energy transfer
D)Decreased radiative recombination lifetime
💡 Explanation
Decreasing oxide thickness increases **quantum tunneling** because a thinner barrier permits wavefunction penetration; therefore, electron transfer rates increase rather than being reduced via quantum confinement increase or affecting other processes without tunneling probability increases at thinner shell levels.
