Luminescent and dosimetric properties of ultrafine alumina ceramics with anion defects

摘要

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 Al_2O_3 single crystals were measured. Dose dependences of the thermoluminescence intensity on a dose of β-radiation were found.
