dc.description.abstractA structured film formed by an active Er³⁺-doped amorphous Al₂O₃ layer located between two amorphous silicon nanolayers (NLs) in as-grown conditions shows an enhancement of the photoluminescence (PL) intensity and lifetime at 1.53 μm of one order of magnitude when compared to a similar Er³⁺-doped film without silicon NLs. The film can be pumped even under nonresonant excitation conditions as a result of a long range energy transfer from the a-Si NLs to the Er³⁺ ions. In addition, the PL shows a single exponential decay with a lifetime value as high as 2.4 ms. The lifetime enhancement is associated with an improvement of the emission efficiency of the Er³⁺ ions.es_ES
