Abstract
Single-phase praseodymium- and ytterbium-doped strontium fluoride solid solutions were prepared by co-precipitation from aqueous nitrate solutions followed by annealing at 600 ◦C. Based on EDX analysis, the content of rare-earth elements in solid phase is slightly higher rather than in initial aqueous solution. All the characteristic praseodymium and ytterbium luminescent bands were present. The most intense luminescence in 800 – 1100 nm range was registered in SrF2:Pr (0.1 mol.%):Yb (10.0 mol.%) solid solution. Using the integrating sphere, the values of the quantum yield were estimated. The maximum quantum yield was 1.1 % for Sr0.9495Pr0.0005Yb0.05F2.0505 solid solution.
