Growth, optical spectroscopy and Judd–Ofelt analysis of Pr-doped BaY2F8 monocrystals

This work is devoted to the study of BaY2F8 crystal, doped with different concentrations of trivalent praseodymium ion in the range from 0.3% to 3%. Spectroscopic properties of these materials showed a large dependence on two parameters: dopant concentration and temperature. Judd–Ofelt model analysis of absorption and emission spectra revealed the potential of our materials as promising blue laser emitters.
