Abstract

We present a model for the calculation of the emission spectra of localized excitons in Zn_1-xCd_xSe quantum wells (QWs). The model takes into account the dependence of localization energy (E_loc) on (1) the lateral size of the islands, (2) the island size distribution, and, (3) the exciton island population as a function of temperature. The model includes exciton migration assisted by acoustical phonons. The calculation is illustrated for the case of a 10 ML thick Zn_0.8Cd_0.2Se/ZnSe QW.
