The dynamics and stimulated emission processes of the exciton luminescence are studied in quantum wells ( \(Q W s\) ) of the \(\mathrm{Zn}_{1-\mathrm{x}} \mathrm{Cd} \mathrm{Se} / \mathrm{ZnSe}\) system. A multiquantum well (MOW) structure shows an exciton lifetime of \(150-280 \mathrm{ps}\) and a s

We observed stimulated emission originating from light-hole transitions in single Zn 1-x Cd x Se quantum-well structures, using high excitation photoluminescence spectroscopy as a function of temperature and cavity length. We found that the lasing wavelength depends on the cavity length, and can be
