| Abstract: | Exciton dynamics in ZnCdSe/ZnSe quantum-well structures have been studied from luminescence spectra obtained at T=2 K. The energy and phase relaxation times of localized exciton states have been determined from a study of the destruction
of exciton optical alignment by an external magnetic field and direct measurements of the polarized-radiation decay kinetics
in the picosecond range. The exciton polarization lifetimes measured by two independent techniques are found to be in a good
agreement.
