Abstract

MBE grown MnS layers with different thicknesses have been studied by time resolved photoluminescence spectroscopy. The temporal evolution of the internal Mn2+ (3d5) luminescence is measured over 3 orders of magnitude in intensity. The decay curves obtained reveal a surprising but distinct dependence on the layer thickness with longer lifetime than thinner layers. The observed non-exponential behavior of those time transients can be well described by an energy diffusion model within the 3d states of the manganese subsystem and a subsequent dipole-dipole energy transfer to radiationless centers. © 2010 Elsevier Ltd.
