报道了AlN陶瓷的光学、闪烁和剂量学性能。AlN样品是SHAPAL，主要用于散热器应用的Tokuyama Corp.的商品。从紫外到近红外波长，其显示出0.02 - 1%的透射率，具有可见的半透明外观。在光致发光（PL）中，它主要在340和550 nm附近有两个发射带，主要衰减时间分别为0.92和0.24ns。X射线诱导的放射发光光谱显示340 nm处有较强的发光。作为剂量计性质，研究了热刺激发光（TSL），并且在80和320°C处出现辉光峰。研究了辐照剂量与热释光强度之间的线性关系，AlN陶瓷在0.002 ~
Optical, scintillation, and dosimeter properties of AlN ceramic were reported. AlN sample was SHAPAL, a commercial product of Tokuyama Corp. for mainly a heat sink application. From ultra violet to near infrared wavelengths, it showed 0.02 1 % transmittance with visibly translucent appearance. In photoluminescence (PL), it exhibited mainly two emission bands around 340 and 550nm with primary decay times of 0.92 and 0.24ns, respectively. X-ray induced radioluminescence spectrum was investigated and 340nm peak showed high emission intensity. As a dosimeter property, thermally stimulated luminescence (TSL) was studied and glow peaks appeared at 80 and 320°C. The linearity between the irradiated dose and TSL intensity was studied and AlN ceramic exhibited a good linear response from 0.002 to
