Relaxation scheme for electronic excitations in an insulator: e, electrons; h, holes; ph, phonons; hν, photons; V
k , self-trapped holes; STE, self-trapped
excitons; c n
, ionic centers with charge n. Density of states is represented by grey and white areas for electrons and holes respectively (courtesy A. Vasiliev)
