VUV and UV fluorescence and absorption studies of Pr³⁺-doped LiLuF₄ single crystals

Abstract

The laser-induced fluorescence spectrum of LiLuF₄:Pr³⁺ single crystals, pumped by an F₂ pulsed-discharge molecular laser at 157 nm, was obtained in the VUV and UV regions of the spectrum at room temperature. A number of new fluorescence peaks were observed for the first time to our knowledge. They were assigned to the dipole-allowed transitions 4f5d → 4f² of Pr³⁺ ion. In addition, the absorption spectrum of the crystal samples was recorded. The positions of the bands with the 4f5d configuration were found to be 46 412, 53 267, and 63 397 cm⁻¹ from the ground state, ³H₄, of the Pr³⁺ ion. The edge (onset) of the 4f5d bands was at 45 100 cm⁻¹.
