摘要：

Ti,Mg:alpha-Al2O3 transparent ceramics were successfully fabricated by conventional sintering process under vacuum condition. The SEM micrographs showed that TiO2 effectively inhibited excessive grain growth of Ti,Mg:alpha-Al2O3 transparent ceramics as sintering proceeds. The fluorescence spectra, thermoluminescence and optically stimulated luminescence of Ti,Mg:alpha-Al2O3 transparent ceramics were compared to its single crystals. The influence of different content of TiO2 on the thermoluminescence and optically stimulated luminescence of Ti,Mg:alpha-Al2O3 transparent ceramics were studied. The results showed that the thermoluminescence peaks began to shift to lower temperature with increasing content of TiO2, and the intensity of thermoluminescence peaks increased. The integral luminous areas of OSL curves increased with the increasing content of TiO2. (c) 2013 Elsevier B.V. All rights reserved.
