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. Witryna16 cze 2010 · The calculated results show that Yb atom always prefers capping on the surface site of the silicon frame and no cagelike geometries are found up to n = 13, … hidden riches nora roberts

Witryna7 lip 2024 · Yb-substituted CaF 2 exhibits an anomalous red-shifted luminescence after UV excitation, attributed to the relaxation of impurity trapped excitons (ITE). CaF 2:Yb is the archetype system for this model, in which the Yb 2+ ions can be excited into a long-lived (ms) exciton state. Upon de-excitation, the emission intensity should be … WitrynaAn impurity, present in SBECD, has been shown to be an alkylating mutagenic agent with evidence for carcinogenicity in rodents.
