Аннотация
We have synthesized single-phase powders of Ca1−x−yYbxPryF2+x+y solid solutions with an average particle size of about 35 nm by co-precipitation from aqueous nitrate solutions. After annealing at 600 ◦C during 1 hour, the particle size was increased up to 150–200 nm. Individual luminescence bands of praseodymium are distinguishable in the luminescence spectrum. The intensity of the luminescence of ytterbium increased by a factor of 1000 in comparison with the unannealed samples. The highest luminescence intensity of ytterbium was detected for the Ca0.9495Yb0.0500Pr0.0005F2.0505.
