The theory of an exciton with a spatially separated electron and hole (the hole is in the quantum dot volume, and the electron is localized at the outer spherical quantum dot-dielectric matrix interface) is developed within the modified effective mass method. The effect of significantly increasing the exciton-binding energy in quantum dots of zinc selenide, synthesized in a borosilicate glass matrix, relative to that in a zinc-selenide single crystal is revealed.
