Optical Spectroscopy of Li<sub>6</sub>Y(BO<sub>3</sub>)<sub>3</sub> Single Crystals Doped with Dysprosium
The energy levels of Dy<sup>3+</sup> ions have been determined in lithium yttrium borate (Li<sub>6</sub>Y(BO<sub>3</sub>)<sub>3</sub>) single crystals in a wide spectral range between 3000 and 40,000 cm<sup>−1</sup> using optical absorption...

| description | The energy levels of Dy<sup>3+</sup> ions have been determined in lithium yttrium borate (Li<sub>6</sub>Y(BO<sub>3</sub>)<sub>3</sub>) single crystals in a wide spectral range between 3000 and 40,000 cm<sup>−1</sup> using optical absorption and luminescence spectroscopy, which also allow for an analysis of the ground state. The crystal field splittings of the <sup>6</sup>H<sub>15/2</sub> ground state and all excited states up to the <sup>4</sup>F<sub>7/2</sub> manifold were obtained at a low temperature, based on luminescence (T = 4.2–78 K) and absorption (T = 8–100 K) measurements, respectively. The numbers of experimentally observed Stark sublevels are in agreement with those expected theoretically for Dy<sup>3+</sup> ions occupying a single low symmetry (C<sub>1</sub>) site. |
