Abstract

Time-resolved photoluminescence spectra in semiconductor quantum wells is discussed. It shows a distinct 1s resonance, which is independent of the existence of bound excitons. A microscopic analysis identifies electron-hole plasma and exciton contributions. The excitonic emission is extremely sensitive to details of the electron-hole-pair population at low temperatures and low densities, making it possible to identify even minute fractions of optically active excitons.
