Rezumat

We consider the photoluminescence spectra for self-assembled CdSe quantum dots on the ZnSe substrate. The spectra of optical phonons are derived for these structures. The PL features due to the LO-phonon-assisted transitions from the remnant-layer exciton state to the quantum-dot exciton state are analyzed. They compare well with the recently observed fine structure of PL in self-assembled CdSe quantum dots formed by thermally activated surface reorganization.
