Which outcome occurs when a photon excites a non-valence electron within a zinc oxide quantum dot?

💡 Explanation

Photoluminescence occurs because electron transitions release energy in the form of lower-energy photons after photoexcitation. Subsequent radiative recombination leads to photon emission during relaxation, rather than non-radiative processes or plasmon excitation; therefore, photoluminescence explains this de-excitation phenomena.
