Polaron Model of Traps and their Activation Energies in KBr Crystals

The activation energy spectrum of traps in KBr crystals has been studied by the thermoluminescence (TL) methods in the temperature range of 80-450 Рљ. The energies of thermal activation of traps in KBr were found to form an oscillator-like series , with the vibrational quantum energy 0.078В eV (629В...

description The activation energy spectrum of traps in KBr crystals has been studied by the thermoluminescence (TL) methods in the temperature range of 80-450 К. The energies of thermal activation of traps in KBr were found to form an oscillator-like series , with the vibrational quantum energy 0.078 eV (629 cm – 1). Using the generalization of the data on other investigated alkali halides crystals the early-proposed model of the TL in alkali halides based upon two-stage recombination of the H-centers was confirmed. The energy of the quantum in oscillator regularity corresponds to the local vibration mode of the halide molecule .
