    • Abstract

       

      The observed fluorescence and absorption spectra of single crystals of KCl and KBr doped with praseodymium (Pr) show that the rare earth enters substitutionally as Pr3+ in these lattices. However, the site symmetry of the ion has at most a twofold axis. This is shown by the fact that thej-degeneracy of its energy levels is completely removed. Fluorescence is observed to occur only from3P0 level to3F2, 3, 4 and3H6 levels. The overall Stark splitting shows that the Pr3+ ion experiences a stronger field in these matrices than in LaCl3 or LaBr3.
