Time-resolved magneto-photoluminescence spectroscopy is applied to elucidate dynamics of excitons in GaAs/AlGaAs/ZnSe/ZnCdMnSe heterovalent double quantum wells (QW). An essential slowdown of the recombination rate was observed, resulting from exciton localization due to the compositional disordering at the AlGaAs/ZnSe heterovalent interface. It was found that both exciton lifetime and spin lifetime can be controlled by varying the detuning of the single-QW electron levels. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
