Abstract

The sensitization mechanism of Er3+ ions by sub-nanometric AuN aggregates formed in silica by sequential ion implantation has been investigated by room temperature photoluminescence characterizations. Er–Au co-implanted samples with different Au and Er relative concentrations have been studied. The results allowed to point out a correlation between the luminescence properties of the molecule-like AuN nanoclusters and the Er sensitization effect and to definitely prove the short-range nature of the energy-transfer process.
