Annotation

Praseodymium- and ytterbium-doped calcium fluoride powder samples were prepared by co-precipitation from aqueous solutions followed by annealing at 600 ?C. Phase and microstructure analyses of these fluorite-type solid solution samples were carried out by X-ray diffraction (XRD) and scanning electron microscopy (SEM), which have demonstrated the average particle size to be about 30 nm, ∼100 nm after drying at 45 ?C and annealing at 600 ?C, respectively. The fluorescence studies under 443 nm excitation in 3 H 4 – 3 P 2 band of Pr 3+ ions allowed us to determine the optimal chemical compositions of CaF 2 :Yb:Pr samples with the high Pr 3+ - > Yb 3+ energy transfer efficiency exceeding 90% and down-conversion luminescence efficiency up to 50%. The optimal compositions are: Yb:Pr = 10.0:0.05; 10.0:0.1; and 5.0:0.05 mol%. This confirms that the energy transfer from praseodymium to ytterbium occurred via quantum cutting mechanism, and the optimal composition for highly efficient phosphor app
