摘要：

The sensitization mechanism of Er3+ ions by sub-nanometric Au-N 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 Au-N nanoclusters and the Er sensitization effect and to definitely prove the short-range nature of the energy-transfer process. [GRAPHICS] Efficient sensitization of the Er3+ luminescence in silica is obtained by energy-transfer from ultra-small Au-N nanoclusters. (C) 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
