Abstract
This work establishes for the first time that imposing of permanent magnetic field ledt o shift of peaks in ranges of photoluminescence of nanopowders CaF2 and BaF2. Ranges of shift of peaks to the red area of a spectrum depended on the size of magnetic field. A transformation of peaks occurs as a result of interaction of own magnetic field of nanofluorides with external magnetic field caused by structural defects of nanopowders. Deconvolution of spectra allowed to identify the split of the first peak of both nanofluorides to a quadruplet, and the second to a doublet at the size of magnetic field of 0.1 T. At increase in magnetic field the quadruplet of the first peak disappears, and the doublet of the second significantly differs for ferromagnetic CaF2 and para-ferromagnetic BaF2. Besides, spectra of both nanofluorides contain peaks at 616 nm that aren’t observed in the field of 0.1 T but appear in the field of 0.15 T, and are possibly caused by the center of coloring.
