abstract

  • AbstractLow‐temperature kinetics of the energy transfer of localized optical excitations in a nitrogen‐doped GaP bulk sample with a nitrogen content of 2.1 % is studied by means of time‐resolved spectroscopy. Both spectral and time dependence of the photoluminescence decay are described quantitatively in a time range from nanoseconds to microsecond by a phenomenological theory of hopping and energy relaxation of localized excitons. The density of localized states and their energy distribution are determined by comparison of experiment and theory. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
