Excitation and emission spectra of NaCl-Eu, KCl-Eu, KBr-Eu and W-Eu phosphors were investigated. Similarly, the optical flash, thermo-luminescence and absorption spectra of a few of these phosphors after x-excitation were examined. It is shown that recombination luminescence of alkali halide phosphors activated with europium is due to the release of electrons from trapping centers. Sensitized luminescence of manganese in NaCl-Eu phosphor with a resonance mechanism of energy transfer is revealed. (auth)
