Abstract
Thermostimulated luminescence and ESR spectra of MgO crystals with dif ferent Fe ions concentrations, which were subjected to thermochemical treatment are studied It has been shown that for samples with high con centration of Fe ions, depending on the time of storage, drop of the T SL maximum intensity at 400 K is due to the decrease of concentration of the emission centres (F, Cr2+) as a result of tunnel transitions of electrons from these centres to intrinsic Fe3+ ions.
