Energy transfer between Ag+ and OH- impurities KMgF3 crystals

Photoluminescence spectra of the perovskite-like KMgF3 doped with both Ag+ and OH- impurities, measured in the energy range 3-7 eV under excitation at 9.2 eV with Synchrotron light, reveal an energy transfer process from Ag+ to OH- ions.
