dc.description.abstractArsenic-doped isotopic 74Ge nanocrystals (nc-74Ge) embedded in amorphous SiO2 films were prepared by neutron transmutation doping (NTD) and the influence of the As additive on the optical properties of the samples was investigated. The optical results showed that the original nc-74Ge photoluminescence (PL) (∼620 nm) blue-shift and PL quenching could be seen by the appearance of Auger-like recombination channels, while the increase in PL was produced by neutron irradiation and a second annealing, not by the As impurities.
