← ScienceWhich consequence results when degeneracy is lifted in quantum dot energy functions?
A)Sharp emission spectral lines appear✓
B)Increased electron-phonon scattering occurs
C)Overall photoluminescence intensity decreases
D)Quantum confinement effects are eliminated
💡 Explanation
Lifting degeneracy splits energy levels, leading to transitions at specific energies; this causes defined spectral lines due to the quantum confinement effect, rather than broadened spectra, because distinct states are now resolvable, therefore the lines sharpen rather than broaden.
