摘要：

We demonstrate that resonant Rayleigh scattering can dominate the secondary emission of quantum wells for much longer times than previously reported. Coherent manipulation of the quantum state of the system allows cancellation of the beats preserving subpicosecond time resolution. The main features of the rise and decay of the emission are unmasked showing that the latter can be governed by excitonic dephasing. [S0163-1829(99)01631-8].
