The first experimental results obtained by the ion beam-induced luminescence technique from the ceramic bodies of ancient tiles are reported in this work. The photon emission from the ceramic bodies is related to the starting minerals and the manufacturing conditions, particularly the firing temperature and cooling processes. Moreover, the results indicate that this non-destructive technique, performed under a helium-rich atmosphere instead of an in-vacuum setup and with acquisition times of only a few seconds, presents a promising alternative to traditional, often destructive, compositional characterisation methods. Additionally, by adding other ion beam-based techniques such as PIXE (Particle-Induced X-ray Emission) and PIGE (Particle-Induced Gamma-ray Emission), compositional information from light elements such as Na can also be inferred, helping to also identify the raw materials used.
本文报道了通过离子束诱导发光技术从古代瓷砖陶瓷体获得的首批实验结果。陶瓷体发出的光子与起始矿物和制造条件有关，特别是烧制温度和冷却过程。此外，结果表明，这种无损技术在富氦气氛而非真空环境下进行，采集时间仅需几秒，是传统的、通常具有破坏性的成分表征方法的一种有前景的替代方案。此外，通过添加其他基于离子束的技术，如粒子诱导X射线发射（PIXE）和粒子诱导γ射线发射（PIGE），还可以推断出诸如钠等轻元素的成分信息，有助于识别所使用的原材料。
