耀州窑瓷器的热释光特性研究及年代测定

Research on thermal luminescence characteristics and the production age of Yao-zhou kiln porcelain

耀州窑是中国古代北方青瓷的代表,在青瓷发展史上占有重要位置。为了深入研究耀州窑青瓷的热释光特性,提高热释光测定耀州窑瓷器年代的准确性,本研究测试了16件耀州窑瓷片。前剂量饱和指数法被应用于测定耀州窑青瓷的古剂量。运用厚源计数法测量瓷胎与埋藏环境土壤样品的α计数、X射线荧光光谱仪测量K含量等方法进行年剂量测定;得到了针对测量耀州窑瓷器样品的热释光特性参数,优化了测量程序,获得了更适用于耀州窑地理环境的年剂量数据,减小了未来样品的取样量,为更好地研究与鉴别其真伪提供了有效的科学依据与方法。

The Yao- zhou kiln,as a representative production site for ancient Chinese northern celadon, occupies an important position in the history of the development of Chinese porcelain. By further study of thermal luminescence （TL） characteristics of Yao- zhou kiln porcelain, the accuracy of TL dating of Yao- zhou porcelain was improved. This study tested 16 Yao-zhou porcelain. The predose saturation index method was applied to measure the paleodose of Yaozhou kiln porcelain. The thick source counting method was applied to measure the α counts of porcelain body and buried soil samples and X -ray fluorescence was used to measure K content. The annual dose of every sample was measured. TL characteristic parameters and procedures were optimized for measurement of Yao - zhou porcelain samples. The annual geographic environmental dose of theYao - zhou kiln was obtained. All of these measures will reduce the amount of sample needed in the future. The study provides effective scientific basis and methods for better research and authentication of Yao - zhou kiln porcelain.
