摘　　要：应用扫描电镜能谱仪和激光显微共聚焦拉曼光谱仪对西安东郊唐墓出土彩绘陶俑表面颜料的微观结构和组成进行科学分析。研究发现,这批陶俑表面颜料均为无机颜料,红色、铁红色、绿色、白色、黑色、桔色颜料的显色成分分别为朱砂、赤铁矿、孔雀石、铅白、炭黑、铅丹。其中,朱砂成分单一,无伴生矿物石英,可以确定是经过加工纯化或者人工合成的;黑色颜料的晶粒尺寸在纳米范围。分析结果为这批陶俑彩绘颜料的鉴定、保护修复工作提供科学依据。Scanning electron microscopy(SEM) and confocal micro-Raman spectroscope(CMRS) were used to analyze the pigment composition of pottery figurines unearthed from Tang Dynasty Tomb in the Eastern Suburbs of Xi’an. The pigments were composed of inorganic mineral ones, with the red pigment of the pottery surfaces to cinnabar, the iron red pigment to be hematite, the white pigment to be white lead and the black pigment to be charcoal, while the orange one was minimum. The composition of the red pigments(cinnabar) is pure without quartz crystal, probably because it was purified or synthesized. The crystal size of charcoal is possibly at nanometer scale. This analysis result provides a scientific basis for pigment identification, cultural relic conservation and restoration in the future study.
