Abstract
Three Pr:PbF2 single crystals with different doping concentrations (0.1, 0.5 and 1.0 at.%) have been detailed investigated to figure out the effect of doping concentration on spectroscopic properties for the first time. The XRD study shows the crystals belong to the cubic system and the lattice parameter of 1.0 at.% Pr:PbF2 crystal is 5.9336 Å. The maximum phonon energy of three crystals was speculated as low as 259 cm−1 through Raman spectra. The absorption and fluorescence spectra of the Pr:PbF2 crystals with different doping levels were recorded and analyzed with the J-O theory. The maximum absorption cross-section at 443 nm and maximum emission cross-section at 482 nm can be obtained as 1.00 × 10−20 cm2 and 1.08 × 10−20 cm2 in 1.0 at.% Pr:PbF2 crystal, respectively. The gain cross-sections of the Pr:PbF2 crystals become positive in a range of 482–497 nm once the population inversion level reaches 30 %. The maximum fluorescence lifetime of 3P0 energy level was found as 33 μs in 0.1 at.% Pr:PbF2 crystal. On the whole, the spectroscopic performance of Pr: PbF2 crystal would be improved by increasing the Pr3+ doping level appropriately.
