Abstract:

The methods of pulsed cathodoluminescence have been used to study compacted powders and ceramics containing different phases of aluminum oxide. An intensive luminescence of the samples under study in the visible, NIR, and UV regions of the spectrum has been found. The luminescence bands are very broad and include a few components. The number of the bands depends on the phase composition of the samples. The oxygen vacancies, which capture one or two electrons, produce luminescence centers in the near IN region. The most probable in the visible region is the luminescence of aggregate defects, impurities, and surface centers (C) 2011 Elsevier B.V. All rights reserved.
