摘要：
Resonant photoexcitation of a predominately homogeneously broadened exciton line in a GaAs quantum well results in a nonexponential time-resolved photoluminescence decay transient due to the decrease in the exciton-exciton scattering contribution to the homogeneous linewidth, GAMMA(h), as the exciton population decays. This result confirms the theoretically predicted relationship between the exciton radiative recombination lifetime and the homogeneous linewidth (and coherence area) of the exciton state.
