| 摘 要： | 分析和确认古代颜料的成分是文物研究中的一项重要工作。为对四个来自不同地区的含Cu、As元素的绿色颜料进行鉴别,应用拉曼光谱仪并辅助以扫描电镜能谱分析仪(SEMEDX)和X射线衍射仪(XRD)进行研究。结果表明其分别为墨绿砷铜矿、氯砷钠铜石以及巴黎绿。对其来源分别进行了讨论,因巴黎绿在国内青铜修复和古建彩画当中的大量应用,过去对于含有Cu、As的绿色颜料通常鉴定为巴黎绿。墨绿砷铜矿和氯砷钠铜石为在文物彩绘中新发现的两种矿物颜料,为绿色颜料的鉴定提供了新的思路。

| Abstract: | Raman microscopy(RM), scanning electron microscopy with energy dispersive Xray spectroscopy (SEMEDX) and Xray powder diffraction (XRD) were applied to analyze four green pigments collected from different places. The studies indicated that the four samples all contained both Cu and As and as cornwallite [Cu5(AsO4)2(OH)4], lavendulan [NaCaCu5(AsO4)4Cl·5H2O] and emerald green [Cu( CH3COO)2·3Cu(AsO2)2] In China, emerald green was once widely used in bronze repairs and for coloring buildings. A green pigment containing the elements Cu and As was once generally considered to be emerald green, but the identification of cornwallite and lavendulan in ancient artifacts suggests new possibilities. |
