Popis: The irradiation effect on Aluminum nitride (AlN) (AlN-a (99 wt% AlN +0.9 wt% O), AlN-b (94.9 wt% AlN +4.3 wt% Y 2 O 3 ), AlN-c (59.5 wt% AlN +40% BN)) was studied by thermoluminescence method from the viewpoint of defect production. Two main thermoluminescence peaks were observed around 400 and 600 nm for these samples. For γ irradiation, it was found that the peak position of the thermoluminescence peak around 400 nm varies between 390 and 450 nm at the temperature range from 500 to 873 K for AlN-b and c. It was considered that the varying of the peak position was influenced by the transformation of the two kinds of oxygen-related complex defects. For electron irradiation, the relative intensity of the peak around 400 nm was found to decrease with the increasing dose of electron irradiation.
