%X The generation,relaxation,and recombination of hot carriers in ZnSeTe/ZnTe type II multiple quantum well (MQW) structures are investigated using photoluminescence (PL) spectra and the femtosecond pulse pump-probe technique.The generation of hot carriers in barrier layers and well layers is observed by time-resolved differential transmission spectra.The cooling time of hot carriers in ZnTe layers is about 10ps.Carrier capturing from the ZnTe barrier layer to the ZnSeTe well layer is also in the time scale of 10ps.
