Abstract

The energy of an electron-hole pair in laser-excited semiconductor microcrystallites is computed with plasma screening and dielectric polarization taken into account. A strong excitation-induced blue shift of the absorption is predicted which causes a large optical nonlinearity for crystallite sizes exceeding the bulk-exciton Bohr radius.
