Luminescent and Dosimetric Properties of Ultrafine Alumina Ceramics with Anion Defects

Abstract

Abstract. Ultrafine oxygen-deficient alumina ceramics was obtained by high-temperature annealing of nanopowder compacts in a vacuum in a strong reducing medium. The spectra of pulsed cathodoluminescence, photoluminescence, electron paramagnetic resonance and thermoluminescence of the synthesized ceramics and anion-defective Al2O3 single crystals were measured. Dose dependences of the thermoluminescence intensity on a dose of β-radiation were found.
