利用激光诱导击穿光谱分析法检测古建筑砖瓦成分

Element Analysis of Blue Brick and Tile of Ancient Architecture with Laser-induced Breakdown Spectroscopy

利用激光诱导击穿光谱技术对三个不同地方和古建筑的青砖瓦试样进行检测分析。在对样品造成较小损伤的的前提下,获得了各样品的特征光谱,发现青砖青瓦中含有Ca,Fe,Na等元素,对3种样品不同元素特征谱线强度分析表明不同样品内元素含量存在明显差异。实验结果表明,激光诱导击穿光谱分析法能够对文物损伤很小的情况下,快速的检测文物材料的组成元素及含量,能够为文物材料成分的检测提供一种新的技术参考。

Laser induced breakdown spectroscopy technology was used to analyze samples of three architectures from different provinces. Characteristic spectroscopies were acquired while little damage was made to the sample. It was found that the ancient blue brick and tile contained Ca,Fe,Na and other elements. The intensities of characteristic spectrum of different elements indicated that the element concentrations in the samples differed significantly. The result of our work proved that laser-induced breakdown spectroscopy technology can detect the composition elements and the concentrations of the antique while making little damage to the antique,the validity and simplicity of this method meant that it can have a novel approach to analyze the material composition of the antique.
