| Abstract: | Single crystal of KZnF3: Eu3+ has been grown by means of Bridgman-Stockbargertechnique in Ar atmosphere. The emission and excitation spectra of europium ion weremeasured. The results show that a small amount of Eu2+ exists in the crystal. The existence ofEu2+ ions was also confirmed by ESR data. The valence change of Eu ions during the crystalgrowth is due to unequivalent substitution of Eu3+ ions for the lattice ions. The sites possiblyoccupied by Eu ions in this crystal were also discussed. |
