Abstract: | Alumina ceramic doped with Mg and Cr is produced at high-temperature sintering under vacuum at varying annealing temperature and dopant concentration. A differential thermal analysis, X-ray fluorescence, and X-ray diffraction methods are used for sample characterization. The effect of the characteristics described above on the formation of different defects and luminescence centers in the samples was studied with a thermoluminescence method. An increase in the dopant concentration leads to an increase in the pulsed cathodoluminescence intensity of the dopant center in Mg-doped alumina ceramics and a decrease in Cr-doped alumina ceramics. The thermoluminescence intensity for Al2O3:Mg ceramics increases with magnesium concentration growth. The highest thermoluminescence intensity under a pulsed electron beam was obtained for ceramics with chromium (0.1 wt. %) annealed under vacuum at the temperature of 1500 °C for 2 hours. On thermoluminescence curves, one isolated peak at a temperature in the range of 645-665K was registered. © 2020 Author(s). |
