Abstract
The spectroscopic properties of wide-band fluoride Na0.4Lu0.6F2.2 crystals activated by Ce3+ were investigated. The absorption edge for the matrix was found to be at about 9.5 eV. In the 4- to 8-eV region of the absorption spectrum of Na0.4Lu0.6F2.2: Ce3+, all 4f-5d transitions of the Ce3+ ion are observed. In Na0.4Lu0.6F2.2: Ce3+ crystals, ultraviolet/visible emission, reflection and time-resolved vacuum ultraviolet/ultraviolet excitation spectra were recorded at liquid helium and room temperatures.
