摘要

Decay time properties of erbium ions in silicon rich silicon oxide multilayers are reported. A non-exponential time behaviour for the ~4I_(13/2) decay profile is observed and is interpreted in a diffusion-limited model. Furthermore, an appreciable increase of the lifetime of the ~4I_(13/2) is observed when the sample temperature is lower than 50 K. The lifetime dependence of the ~4I_(13/2) as a function of temperature was successfully fitted with a model taking into account the temperature dependence of the energy migration between Er~(3+) ions in the presence of quenching impurities.
