Abstract
In this paper, with the modified Bridgeman method, 1 mol% Ho, x mol% Pr: BaY2F8 (x = 0, 0.2, 0.5, 0.8, 1.2) crystals were successfully prepared and their emission properties were studied. The X-ray diffraction data of the crystals showed that the crystals still maintained the monoclinic structure of the host. The infrared emission spectra showed that the doping of Pr3+ ions weakened the intensity of the emission peak at 2.0 μm and enhanced the intensity of the emission peak at 2.9 μm of the crystals. The optimal doping concentration of Pr3+ ions was 0.5%. As the doping concentration of Pr3+ ions increased, the lifetime of the 5I7 level of Ho3+ ions decreased from 2.03 ms to 0.23 ms, thus promoting particle number reversal and laser operation. As for Ho, Pr: BaY2F8 crystal, the energy transfer efficiency from Ho: 5I7 level to Pr: 3F2 level was calculated to be 88.7%.
