Which outcome occurs when high-energy photons illuminate silicon nanocrystals?

💡 Explanation

Quantum dot photoluminescence appears because the quantum confinement effect drastically alters the electronic structure, causing discrete energy levels and radiative recombination, therefore quantum dots emit specific wavelengths, rather than inducing lattice expansion under illumination.
