Abstract

This article presents the results of a systematic investigation on the identification of minerals used in lacquers. Micro-Raman combined with Infrared spectroscopy can serve as a highly specific and complementary micro-destructive technique for successfully identifying the molecular structure of the minerals. Both 532-nm and 785-nm laser radiations were used to compare the spectral information and to clarify which wavelength was suited to balance the signal to noise ratio. The spectra of fourteen minerals were analyzed and compared in detail, which can provide support for the research on the developmental changes of lacquer materials in different historical periods by establishing an identification method.

摘要

本文介绍了对漆中使用的矿物质的识别进行系统调查的结果。微拉曼结合红外光谱可以作为一种高度特异性和互补的微破坏技术，成功识别矿物的分子结构。532 nm 和 785 nm 激光辐射都用于比较光谱信息并阐明哪种波长适合平衡信噪比。对14种矿物的光谱进行了详细的分析比较，建立了鉴别方法，可为研究不同历史时期漆料的发展变化提供支持。
