Crystal-field effects are very important as far as laser performances of Yb-doped materials are concerned. In order to simplify the interpretation of low-temperature spectra, two tools derived from a careful examination of crystal-field interaction are presented. Both approaches are successfully applied in the case of new Yb-doped materials, namely Ca3Y2(BO3)4 (CYB), Ca3Gd2(BO3)4 (CaGB), Sr3Y(BO3)3 (SrYBO), Ba3Lu(BO3)3 (BLuB), Y2SiO5 (YSO), Ca2Al2SiO7 (CAS) and SrY4(SiO4)3O (SYS). The 2F7/2 splitting is particularly large in these materials and favourable to a quasi-three-level laser operating scheme. Calculations performed using the point charge electrostatic model for these compounds and using a consistent set of effective atomic charges confirm the experimental results. This should permit to use this model in a predictive approach.read more

Polyoxometalate-supported Y- and YbIII-hydroxo/oxo clusters from carbonate-assisted hydrolysis.
TL;DR: Control experiments show that carbonate not only functions in the hydrolysis of Y or Yb(III) ions, it also influences the structure of the complexes by complexation to yttrium and the f-block elements.

TL;DR: In this paper, the meaning of a scalar crystal field strength parameter defined previously [4, 5] is studied and it is shown why, in many cases, it can be used as an indication of the magnitude of the maximum Stark splitting of J-terms for ions in crystals of different structures and site symmetries.
