Luminescence of Sm(sup 2+) ions in non-cubic high pressure alpha phase of divalent fluorides.

摘要

The luminescence spectra of Sm(sup 2+) impurities are characteristic of the local site symmetry and, thus, the bulk crystal phases of SrF(sub 2) and CaF(sub 2). In this study we have used the Sm(sup 2+) luminescence spectra to monitor the (beta)->(alpha) ...
