AbstractA distribution function for localized carriers, f (E, T) = 1/ e(E-Ea)/kBT+τtr / τr, is obtained by solving a rate equation, in which electrical carriers' generation, thermal escape, recapture and radiative recombination are taken into account. Based on this distribution function, a model is developed for luminescence from localized-state ensemble with a Gaussian-type density of states. The model reproduces quantitatively all the anomalous temperature behaviors of localized-state luminescence. It reduces to the well-known band-tail and luminescence quenching models under certain approximations. © EDP Sciences.
