Cui Fengzhu Dong Jian(Changchun Institute of Opties and Fine Mechanies,Academic Sinicea, Changchun, 130022)
Perovskite type single crystals of Eu~- ion doped KMgF_3 have been grown by the Bridgma-Stockbarger technique in Ar atmosphere, Absorption, emission and excitation spectra of the crystal are presented and discussed. High resolution fluorescenee spectrum obtained for the crystal pumped with N_2laser shows that the crystal is many center structure.
