Abstract

New highly sensitive thermoluminescence detectors of broad application on the basis of anion-defective α-A12O3:C single crystals have been developed. The decisive role of non-stoichiometry in forming luminescence properties of crystals has been ascertained by methods of optical, luminescence and exoemission spectroscopy. Detectors possess the following dosimetric properties: sensitivity to gamma radiation 50 times higher than that of LiF:Mg, Ti; low background, dose threshold about 10-6 Gy; a single glow peak at 460 K; blue luminescence band at 420 nm; negligible fading and the possibility of re-use without annealing procedures.
