We study the exciton states in the cubic quantum dots with finite potential barrier at the presence of dielectric mismatch. The dependence of electron and hole ground states as well as exciton binding energy and oscillator strength are found as a function of quantum dot size and dielectric constant of quantum dot and surrounding matrix. The developed theoretical approach has been applied to analyze the peculiarities of exciton spectra in CdTe quantum dots embedded in a variety of dielectric matrices.
