21. The IS-IP transitions involve a change of parity (S to P and vice versa) and are not allowed formally. Its appearance was interpreted as a result of reduced symmetry of the nanocrystal surface or the existence of electric fields from charge trapped in surface states (see ref 22).

28. Auger-like cooling occurs when, for example, the electron transfers its excess energy to the hole through a Coulomb interaction and the hole subsequently cools, by phonon scattering, through the higher density of states in the valence band.
