[en] AlON:C transparent ceramics were prepared by pressureless sintering method with high purity α-Al₂O₃ powder and AlN powder as raw materials, and the same amount of carbon was incorporated into AlON transparent ceramics by atmosphere infiltration method, research the optically stimulated luminescence (OSL) performance of AlON:C transparent ceramics. The OSL decay curves of AlON:C transparent ceramics are exponentially decaying with time, fast at the beginning, and slowly later on. 470 nm blue light cannot empty the optically stimulated luminescence signal, which has a signal accumulation phenomenon. The OSL intensity response curves of AlON:C irradiated under β-ray irradiation are linear to sub-linear and tend to be saturated. The OSL response curve of AlON:C transparent ceramics for β-ray shows an excellent linear characteristic, respectively, in the range of 50 mGy∼50 Gy and 50∼100 Gy; in the range of 50∼500 mGy, it shows an excellent linear characteristic to β-rays and γ-rays. The intensity of OSL under γ-ray irradiation is about 76% of that of OSL under β-ray irradiation. (authors)
