We consider the photoluminescence spectra for self-assembled CdSe quantum d
ots on the ZnSe substrate. The spectra of optical phonons are derived for t
hese structures. The PL features due to the LO-phonon-assisted transitions
from the remnant-layer exciton state to the quantum-dot exciton state are a
nalyzed. They compare well with the recently observed fine structure of PL
in self-assembled CdSe quantum dots formed by thermally activated surface r
eorganization. (C) 2000 Elsevier Science B.V. All rights reserved.
