我们最近将两种XRF（微x射线荧光）方法[微放牧出口XRF （GE-XRF）和共聚焦3D-XRF]应用于日本漆器“Tamamushi-nuri”。实验室放牧出口XRF （GE-XRF）仪器与微型XRF装置相结合。微x射线束是由一个毛细管和一个针孔孔径产生的。显微GE-XRF在不同分析深度下获得了元素x射线图像（二维图像）。然而，直接获得深度选择x射线光谱和二维图像是困难的。使用两个独立的多毛细x射线透镜和两个x射线源（Cr和Mo靶）的3D XRF仪器也应用于同一样品。日本漆器的二维XRF图像显示了元素在不同深度的特定分布，表明“Tamamushi-nuri”漆器具有分层结构。讨论了微型GE-XRF和共聚焦微型XRF方法的优缺点。版权所有©2009 John Wiley & Sons， Ltd
We have applied recently two XRF (micro x-ray fluorescence) methods [micro-Grazing Exit XRF (GE-XRF) and confocal 3D-XRF] to Japanese lacquerware ‘Tamamushi-nuri.’ A laboratory grazing-exit XRF (GE-XRF) instrument was developed in combination with a micro-XRF setup. A micro x-ray beam was produced by a single capillary and a pinhole aperture. Elemental x-ray images (2D images) obtained at different analyzing depths by micro GE-XRF have been reported. However, it was difficult to directly obtain depth-selective x-ray spectra and 2D images. A 3D XRF instrument using two independent polycapillary x-ray lenses and two x-ray sources (Cr and Mo targets) was also applied to the same sample. 2D XRF images of a Japanese lacquerware showed specific distributions of elements at the different depths, indicating that ‘Tamamushi-nuri’ lacquerware has a layered structure. The merits and disadvantages of both the micro GE-XRF and confocal micro XRF methods are discussed. Copyright © 2009 John Wiley & Sons, Ltd.
