Observation of the hyperfine structure and anticrossings of hyperfine levels in the luminescence spectra of LiYF4:Ho3+
Abstract
The first observation of hyperfine and isotope structures, deformation splitting, and level anticrossing in luminescence spectra of crystals is reported, on the example of LiYF4:Ho. All-optical magnetic field sensor is proposed.
