Book Description
We measure the time dependence of the excitonic photoluminescence (PL) in quantum wells (QWs) with well width Lz ranging from 25A to 50A. The samples are AI0.2Ga0.8As/GaAs multiple QWs with 30 periods with decoupled wells and were grown by molecular beam epitaxy (MBE). QWs grown with and without growth interruption at the interfaces are investigated. The excitation is provided by 5 psec pulses from a synchronously pumped tunable dye laser. The PL spectrum is detected by an imaging (i.e. multichannel) photomultiplier with a spectral resolution of 0.5 meV and time resolution (FWHM) of 120 psec.

Book Description
This report discusses the relation between expenmental results and theoretical models suggested so far for the temperature-dependent energy relaxation and recombination of excitons in coupled QWs. Physical conditions are discussed that favour each class of theoretical models.
