摘　　要：为揭示宋代耀州窑深灰、灰白胎橄榄绿青瓷的结构色呈色机理,以宋代耀州窑橄榄绿青瓷为对象,分别采用EDXRF、XRD、XPS、Raman和SEM/EDS等测试方法,分析了化学组成、物相、微观结构对瓷釉的呈色影响。结果表明,深灰胎橄榄绿青瓷釉的Fe2+/Fe3+比值小于灰白胎从而呈色更偏黄绿。深灰胎橄榄绿青瓷釉的气泡和分相所产生的米散射是其乳浊的主要原因,瑞利散射是其呈橄榄绿色的源动力之一。灰白胎橄榄绿青瓷釉的呈色主要是其非晶结构色与Fe元素化学色的耦合。橄榄绿青瓷胎内Ti元素的含量越高,胎色越暗,透过率越低,也正是深灰胎橄榄绿青瓷比灰白胎橄榄绿青瓷白度低的原因之一。;In this work,the Song Dynasty olive-green celadon of the Yaozhou Kiln was studied.In order to investigate the mechanism of the coloring in the olive-green celadon with dark gray body and graywhite body,the effect of chemical composition,phase and microstructure on the coloring are analyzed by EDXRF,XRD,XPS,Raman and SEM/EDS.The results indicate that the Fe2+/Fe3+ratio of the dark gray body olive-green porcelains glaze is smaller than that of the gray-white body porcelains glaze and the color is more yellowish green.The Mie scattering caused by the bubbles and phase separation of the dark gray body olive-green celadon glaze is the main reason for its opacification.Rayleigh scattering is one of the sources of its blue color.The color of celadon glaze with gray-white body is mainly due to the coupling of its amorphous structural color and the chemical color of Fe element.The higher the Ti content in the celadon body,the darker the body color and the lower the transmittance,which is one of the reasons why the olive-green celadon with dark gray body has a lower whiteness than the olive-green celadon with gray-white body.
