Spectroscopic properties of trivalent praseodymium in barium yttrium fluoride

We have conducted a spectroscopic investigation of Pr3+ in barium yttrium fluoride (BaY2O8). Two doping concentrations were used: BaY2F8:Pr3+ (0.3%) and BaY2F8:Pr3+ (1%). The measurements included absorption, luminescence under continuous and pulsed excitations, and thermal effects on some sharp lines. The experimental results were used to characterize this system.
