Transparent ceramics of Al2O3 doped with different concentrations of Mg2+ ions (0.001, 0.01, 0.1 and 1.0%) were synthesized by the Spark Plasma Sintering (SPS) method, and scintillation and dosimetric properties were investigated. Under X-ray irradiation, all the samples showed emission peaks around 310, 380 and 693 nm. Based on the measured scintillation decay times and previous studies, the origins of the emission peaks at 310, 380 and 693 nm were attributed to F+ centers, F centers and Cr3+ impurity ions, respectively. The 0.1% Mg-doped sample showed a glow curve consisting of peaks around 50, 105, 135, 230, 350 and 400 oC. All the samples had a linear TSL response in a dose range from 0.1 to 1,000 mGy.
