We present a study of the luminescence decay of free excitons and electron-hole drops performed in pure Si in a rather broad temperature range. We get the exciton and drop lifetimes but, to interpret our results, we have to consider that the excitondrop system is not spatially homogeneous. We propose also to take into account the exciton recombination at the sample surface to explain the observed non exponential exciton decay.
