Abstract:

Oxygen-deficient alumina ceramics with blue luminescence was synthesized in reducing medium (vacuum, presence of carbon) from nanopowder at varying temperatures and annealing time. The structure of the samples, particle size distribution, changes in mass of the samples at different synthesis temperatures were studied. In the obtained ceramics the spectra of photoluminescence are registered in the band centered at 420 nm, which is associated with the F-centers created by oxygen vacancies. The luminescent intensity grows with increasing temperature and annealing time. The thermoluminescence curves feature two peaks whose intensities depend on the temperature of the ceramics synthesis. Dose response of the thermoluminescence peaks of alumina ceramics synthesized at 1700 degrees C was measured under beta-irradiation. (C) 2016 Elsevier Ltd. All rights reserved.
