摘要：

We present time resolved photoluminescence supported by k.p modeling of type II quantum dots. In the measured spectra two effects were observed; an initially fast decay time rises dramatically as the number of carriers is depleted, which reduces the optical matrix element, and at the same time, a strong red shift of the emission wavelength is observed.
