Abstract

Spectra and the transients of the photoluminescence (PL) of undoped and Er-doped size-controlled nanocrystalline Si/SiO 2 multilayered structures with mean nanocrystal size were investigated. The PL spectra of the Er-doped structures show several dips separated by the energy of Si TO-phonon, at low temperature. The structures are also bound to the transition energies between the second and third excited states to the ground state of Er 3+. This efficient sensitizing of the Er-related luminescence is explained by the structural properties.
