On the Thermoluminescence Mechanism of Non-Doped Corundum Monocrystals with Defect Structure

An investigation was carried out into the distribution of optical absorption, radioluminescence and thermostimulated luminescence (TSL) in large corundum crystals with defects. The dependence of energetic and stochastic parameters of the TSL process on stimulation temperature was analysed for detectors cut from fixed crystal points. TSL, proceeding by the mechanism of structural thermally initiated rearrangements and pure centre structures, was shown to provide for the occurrence of a unique set of operating parameters for ionising thermoluminescent detectors made of this material.
