The aim of this work is to check if Yb 3+ ions can be used as sensitizers for the 4 I 13/2 - 4 I 15/2 emission of Er 3+ ions at 1.54 μm in silicon-rich silicon oxide (SRSO). To answer this question, photoluminescence excitation (PLE) experiments were performed on the Er 3+ emission in a wide range of excitation wavelengths. The PLE …

WitrynaThe concentration of Yb 3+ ions increases monotonically with the ytterbium content, while a significant fraction of ytterbium ions remains in a nonmagnetic Yb 2+ state. This is explained within the electronic band-structure model, assuming the ytterbium-derived donor states form an impurity band in the vicinity of the valence-band top.
