We present experimental evidence on the donor level related to optical properties of the Er3+ ion in crystalline silicon. Using two-color spectroscopy with a free-electron laser we provide a direct link between the identified level in the bandgap and the optical properties of EP,. The investigation is performed in sublimation MBE-grown Si/Si:Er multinanolayer structure, which allows us to take advantage of the preferential formation of a single Er-related center. Quenching of the Er-related 1.5 mu m photoluminescence, due to ionization of the donor state with energy E-D approximate to 225 meV, is demonstrated.
