← ScienceWhich consequence results when the driving frequency destabilizes within a quantum dot?
A)Electron spin coherence accelerates dephasing✓
B)Phonon bottleneck significantly reduces cooling
C)Exciton population becomes highly monodisperse
D)Fluorescence spectrum loses all anisotropy
💡 Explanation
Electron spin decoherence increases when the pump signal destabilizes because hyperfine interactions become exaggerated from additional noise introducing dephasing; therefore, coherence decays, rather than improved emission anisotropy that would maintain coherence in the radiative decay.
