摘要
作为一种无损分析技术,拉曼光谱近几十年来被越来越广泛地应用于文物艺术品分析和考古学领域。色彩是艺术品的灵魂,颜料分析是研究文物艺术品的一个重要课题。本文利用显微拉曼光谱技术,测量了龙门石窟洞窟中彩绘使用的颜料的拉曼光谱,通过对这些光谱的解析,对颜料的化学成分做出了识别。利用X射线荧光光谱进行的元素分析确定金色装饰为高纯度黄金,扫描电镜分析进一步测出了贴金的厚度。这些分析结果对于进一步开展龙门石窟彩绘的保护和修复有着重要的参考价值。
Abstract
As a nondestructive analytical technique,Raman spectroscopy has been used more and more widely in the field of art and archaeology in the past decades.The analysis of the pigments in ancient artworks is an important issue in this field because colors are always the soul of artworks.In this work,the Raman spectra of the pigments from the color paintings of Longmen Grottos were measured and the results were discussed.All the pigments were identified by comparing the Raman spectra with spectral database of the standard pigments.The golden decoration was proved to be high purity gold by X-ray fluorescence(XRF) elemental analysis and its thickness was obtained by scanning electron microscope(SEM) analysis.The results were considered to be of essential importance for further restoration and conservation for the color paintings of Longmen Grottos.
