摘要
本文通过对瓷釉玻璃态中Si-O结构弯曲、拉伸振动拉曼光谱的测量与分析,对故宫院藏的28件宋代官窑青瓷和12件明清仿官青瓷的表面釉层进行了研究。通过计算拉曼光谱中位于500cm-1附近宽带与位于1000cm-1附近宽带的面积比值(Ip值),可以看出明清仿官青瓷的特征与院藏宋官窑瓷器有明显不同,而院藏宋官窑瓷器又可依照烧成温度分为两大类,该结果得到了X-射线荧光分析结果的支持。另一方面,通过瓷釉玻璃相中未熔晶相拉曼光谱的研究,对青瓷釉面效果的成因有所揭示。
Nondestructive Raman analyses have been made on 28 pieces of Guan ware of the Song dynasty and 12 pieces of Guan-typed ware of the Ming and Qing periods which are all collected in the Palace museum.Raman spectra of the glassy phase network were discussed to find the compositions,processing temperature of the glaze.As a result of their glassy features of the Raman spectra,it has be found that the collected Song-dynasty Guan wares of the Palace Museum are composed of two classes in accordance to their different processing temperatures,which is also in agreement with the X-ray fluorescence data.On the other hand,Raman peaks of the remained crystals such as quartz and feldspar are of significance to unveil the cause-andeffect relation of the glazes.
