Abstract

Nano-sized silicon crystals have entirely new physical properties which do not occur in its bulk form. Investigation of its photoluminescence properties can explain the mechanism of transferring energy from photoexcited excitons confined in silicon nanocrystals to energy accepting substances via electron exchange mechanism, This excitation process changes the electronic spin structure of the acceptor molecule, which is forbidden in the dipole approximation, and therefore it requires the involvement of photosensitizers.
