; ;
Excitation spectra of KI-SnI/sub 2/ and NaI-Sn at +20 to --150 deg C and NaI-Sn and KI-Pb at --150 deg were studied. The excitation spectra of KI-Sn indicate absorption excitation with a 219 m mu maximum and an increasing intensity at lower temperatures. It was shown that the intensity of 219 and 229 m mu bands increase with increased activator. Interaction processes between excitons and activated centers result in luminescence center excitation and in single ionized or atomic centers in phosphors with divalent activators. (R.V.J.)
