WitrynaAbstract. 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 … Witryna23 wrz 2011 · We demonstrate a direct measurement of the energy levels of impurity-trapped excitons in CaF 2 :Yb 2+.
