采用同步辐射X射线荧光成像和X射线吸收近边光谱技术，对一件景德镇窑元代釉下铜红瓷器的样品进行了测量，研究了铜元素的分布和形态对瓷器颜色的影响。在黑色区域，铜以金属铜颗粒为主，富集在坯釉界面。而Cu则以多价态不规则分布在红色区域。铜在黑、红两色区的分布和形态差异表明，它们是影响铜红釉下瓷颜色差异的主要因素。
A shard of Chinese underglaze copper-red porcelain from the Yuan dynasty (AD 1271–1368) made in the Jingdezhen kiln was measured by synchrotron radiation-induced X-ray fluorescence mapping and X-ray absorption near-edge spectroscopy to investigate the influence of copper element distribution and speciation on the color of porcelain. In black-colored region, copper accumulates at the interface between the body and glaze layers with metallic copper particles as the main speciation. In contrast, Cu is irregularly distributed in the red-colored region with multi-valence speciation. The differences in Cu distribution and speciation in black- and red-colored regions indicate that they are the main factors influencing the different colors of copper-red underglaze porcelain.
