WitrynaThe spectroscopic characterization of ytterbium-doped LiYF4 (Yb:YLF) is revisited and the prerequisite crystal purity to achieve laser cooling below liquid nitrogen temperatures is shown. 8 PDF Understanding and Preventing Photoluminescence Quenching to Achieve Unity Photoluminescence Quantum Yield in Yb:YLF Nanocrystals Witryna1 kwi 2008 · In this work, we study the systematics, at finite temperature, of the formation of local magnetic moments at a Ta impurity diluted in intermetallic Laves phases compounds XFe 2 (X = Gd, Yb). We use an extended two-coupled sublattices Hubbard Hamiltonian, to describe the Laves phases host. The d–d electronic interaction is …

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. 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+. The radically different radiative decay rates of the lowest exciton state and higher excited states enable the generation of a transient photoluminescence enhancement measured via a two-step excitation process.
