The mechanisms of formation of A-radicals in the crystal K2SO4. Calculations established that the excitation of oscillations on the O-H bond in the triplet excitons in the excited state leads to a situation vibronic instability leading to the disintegration of the exciton with the formation of hydrogen atoms and A- radical.
The recombinational luminescence of crystals of K2SO4-Mn2+ and K2SO4-Ni2+ is studied in the article. It is established that impurity ions form the radiation induced centers. The cause of changes of the distribution of lightsum on TSL peaks of a matrix is established. It is proposed that it is related to pre-radiation defeсts in crystals. It is established from this effect that ions of Mn2+ and Ni2+...
