摘要：

Luminescence spectra of Ca0.65Pr0.35F2.35 solid solutions are studied. It is found that, depending on the excitation energy, different kinds of emission centers appear in these spectra. An interconfigurational 4f (1)5d(1) -> 4f(2) luminescence is typical for single Pr3+ ions in tetragonal sites. Data on the structure of the solid solutions show that the emission centers involved in S-1(0) -> 4f(2) transitions can be attributed to Pr3+ ions contained in clusters.
