Z. Naturforsch. 56 b, 697-703 (2001); received April 5, 2001 Multianvil, High-Pressure Synthesis, Borates /3-Ytterbium borate (ö-YbBOi) was synthesized under high-pressure in a Walker-type mul­ tianvil apparatus at 2.2 GPa and 1400 °C. The title-compound crystallizes in the trigonal calcite structure, space group R3c. Single crystal X-ray data yielded a = 492.1(2), c = 1630.5(9) pm, wR2 = 0.034...

36 LLE Review, Volume 97 Fiber laser and amplifier development in the wavelength region near 1 μm has experienced significant progress owing to the exceptional efficiency and gain bandwidth of ytterbiumdoped fibers.1–5 In fact, both ytterbium fiber lasers and amplifiers are becoming more attractive than their bulk counterparts due to their confined spatial mode, impressive bandwidth, good pump ...

We demonstrate electrical tunability of a fiber laser using a liquid crystal photonic bandgap fiber. Tuning of the laser is achieved by combining the wavelength filtering effect of a tunable liquid crystal photonic bandgap fiber device with an ytterbium-doped photonic crystal fiber. We fabricate an all-spliced laser cavity based on the liquid crystal photonic bandgap fiber mounted on a silicon ...

A new oxyiminopyrazole-based ytterbium chelate enables NIR emission upon UV excitation in colorless single layer luminescent solar concentrators for building integrated photovoltaics.

A method based on the superspace approach is presented with the aim of generating a family of modular structures from a single incommensurately modulated structure. This approach based on the variation of the modulation vector q is applied to the generation of the K5Yb(MoO4)4, potassium ytterbium tetramolybdate, family of modular structures. The beta coefficient of the modulation vector q = bet...

Abstract A simple sublimation technology for the lutetium and ytterbium separation was proposed, which already at stage of preliminary experiments showed effectiveness: (a) completeness Yb resulted in short-term thermal annealing is least 98%, distilled product completely free from 177 Lu, no additional preparation repeated irradiation required ; (b) traditional ion-exchange chromatography can ...

The design of sustainable and efficient materials for energy storage degradation environmental pollutants (specifically organic dyes) is a matter major interest these days. For this purpose, cerium- ytterbium-based GO/g-C3N4/Fe2O3 composites have been synthesized to explore their properties, especially in charge devices such as supercapacitors, also photocatalysts the carcinogenic dyes from env...

The ligand triethylenetetramine-N,N,N',N'',N''',N'''-hexaacetamide (ttham) was synthesized with the aim of forming lanthanide complexes suitable as contrast agents for magnetic resonance imaging applications utilizing the chemical exchange-dependent saturation transfer (CEST) effect. It was designed to exclude water molecules from the first coordination sphere and provide a high number of CEST ...
