Abstract:

The thermoluminescence of single crystals of corundum containing anion defects following x-ray and laser excitation is investigated. Its features in the luminescence bands of F, F(+), and Cr(3+) centers are studied. Synchronous measurements of the thermoluminescence and thermally stimulated exoelectron emission are performed by the fractional glow technique following x-ray and laser excitation of the samples. It follows from the results obtained that several traps are active in the temperature range of the principal dosimetric peak (400-500 K). The spectral sensitivity curve contains maxima corresponding to absorption bands of F, F(+), and Al(i)(+) centers. A possible mechanism for the recombination luminescence of F centers is discussed. It is found that the material exhibits high sensitivity to small doses of ultraviolet laser radiation. (C) 1997 American Institute of Physics. {[}S1063-7842(97)01307-X].
