← ScienceWhich outcome is amplified when electrons encounter resonant frequencies within a quantum dot nanocrystal?
A)Enhanced light absorption and emission✓
B)Reduced thermal conductivity
C)Increased electrical resistance
D)Decreased spin polarization lifetime
💡 Explanation
When electrons encounter resonant frequencies, quantum confinement leads to enhanced light absorption and emission because electrons strongly interact with photons at specific energy levels matching the quantum dot's size. Therefore, light emission is amplified rather than conductivity, resistance changes or spin depolarization, each needing distinct mechanisms.
