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 ESRdata. 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.

Key words: Potassium-zinc fluoride, Bridgman-stockbarger technique, Single crystal growth, Europium ion
