Abstract
Low-temperature kinetics of the energy transfer of localized optical excitations in a nitrogen-doped GaP bulk sample with a nitrogen content of 2.1% are studied by means of time-resolved spectroscopy. Both the spectral and time dependences of the photoluminescence decay are described quantitatively on a timescale from nanoseconds to a microsecond by a phenomenological theory of hopping and energy relaxation of localized excitons. The microscopic parameters, which characterize the luminescent states, are determined by comparison between experiment and theory.
