Scintillation and dosimeter properties of Ca-doped MgO transparent ceramics

[摘要] We have synthesized 0.001, 0.01 and 0.1% Ca-doped MgO transparent ceramics by the Spark Plasma Sintering (SPS) method, and then we investigated the optical, scintillation and dosimeter properties. In scintillation spectra, some emission bands appeared around 340, 400, 440, 600 and 750 nm. After X-ray irradiation, all the Ca-doped samples showed TSL with a glow peak similar to 140 degrees C, and the 0.01% Ca-doped sample showed an additional broad peak similar to 250 degrees C. The TSL spectrum consists of a broad peak over 300-500 nm and some peaks around 600 and 750 nm. The TSL response was confirmed to linearly increase with irradiation dose over a dose range from 0.1 to 100 mGy.
