Evaluation of absolute ages and temperatures for burnt archaeological materials using thermoluminescence (TL) and optically stimulated luminescence (OSL)

利用市售的彩色负片（Sueki）对陶片进行x射线照射后，方便地拍摄了一些辐射致发光彩色图像，包括余辉（AG）或辐射磷光（radiophospherescence）和热释光（TL）。所得到的照片，特别是AG彩色图像（AGCIs），显示出各种各样的发射模式，这取决于矿物的种类或陶器的热历史。为了获得更多的定量信息，对考古陶器切片的agci进行了彩色图像分析。两种颜色强度比的关系，如绿/红和蓝/红，被发现清楚地反映了陶器的起源。同时，发光颜色特性与加热温度的关系表明，通过逐步加热其成分-粘土来澄清窑和陶器的热历史。讨论了古陶瓷的物源鉴定和古陶瓷的热历史。在77K辐照下对多种天然石英进行ESR谱测量，基本上确定了除强al中心外，原子氢或氢自由基的存在。升温至室温后，al中心信号明显减弱，同时氢自由基导致esr信号完全消失，氢自由基信号与al中心减少比例呈正相关。在此基础上，证实了oh相关杂质的辐射分解产生的氢自由基可能是辐射诱导al中心的“杀手”，或蓝色热释光（BTL）的主要来源，表明β-石英/三晶石的相变温度对tl -性质的变化起重要作用。随后，还描述了一个包含小型x射线发生器的自动发光测量系统的构造，该系统涉及TL和OSL（光激发发光）。少

Some radiation-induced luminescence color images, including afterglow (AG) or radiophospherescence, and thermoluminescence (TL), were conveniently photographed by means of a commercially available negative color film after the irradiation of X-ray on pottery slices, named as Sueki. The resultant photographs, particularly AG color images (AGCIs), showed a variety of emission patterns dependent on kinds of minerals or thermal history of pottery. The AGCIs from archaeological pottery slices are subjected to the color image analysis to obtain more quantitative information. The relationships of two color intensity-ratios, such as green/red and blue/red, were found to reflect clearly the origin of pottery. While, the dependence of luminescent color properties on the heating temperatures suggests to clarify thermal history of kilns and potteries using stepwise heating of their ingredient-clay.The discussion was made on that provenance identification of ancient ceramics and thermal history of … More kilns could be evaluated using AGCIs from the slices.Basically, the existence of atomic hydrogens or hydrogen radicals besides intense Al-centers was ascertained in ESR spectrum measurements of a variety of natural quartzes after irradiation at 77K.The remarkable decrease of the Al-center signals, coincident with the complete disappearance of ESR-signal due to hydrogen radicals, occurred recognized after warming once up to room temperature, giving positive correlation between the hydrogen radical signals and reducing proportion of the Al-centers. On the basis of these experiments, it was confirmed that hydrogen radicals derived from radiolysis of OH-related impurities could operate as a "killer" of radiation-induced Al-centers, or main origin of blue thermoluminescence (BTL), suggesting important role of a phase-transition temperature of β-quartz/tridymite to the TL-property changes.Subsequently, a constraction of an automatic luminescence measuring system incorporated a small X-ray generator, involving both TL and OSL (Optically Stimulated Luminescence), is also described.
