Abstract
The influence of the electron-LO-phonon coupling on energy spectrum of the low-lying states of an exciton in parabolic quantum dots is investigated as a function of dot size. Calculations are made by using the method of few-body physics within the effective-mass approximation. A considerable decrease of the energy in the stronger confinement range is found for the low-lying states of an exciton in quantum dots, which results from the confinement of electron-phonon coupling.
