Which mechanism impacts semiconductor quantum dot emission wavelength based on dot size?

💡 Explanation

When the quantum dot size decreases, quantum confinement increases because electrons are forced into smaller regions, leading to higher energy levels of orbitals, thus emitting shorter wavelengths. Therefore, quantum confinement dictates wavelength rather than plasmon resonance, phonon scattering, or Auger recombination, which involve alternate processes.
