Abstract
The polaron effects in quantum dots are investigated theoretically. It is shown that the exciton polaron energy is large in materials with d egenerate valence band. This energy increases with decreasing dot radi us. In the strong confinement regime the electron-hole pair can create significant polarization of the medium in ionic crystals. This polari zation should manifest themselve in multiphonon interband transitions and large Stokes shifts of the optical lines.
