    Application of Raman Spectroscopy to the Noninvasive Identification of Jade

    • 摘要: 通过对软玉及相似玉石蛇纹石玉、石英岩玉、大理岩玉、白色玻璃的拉曼光谱进行测试与研究,得到软玉具有由Si—O振动引起的特征拉曼位移672,930,1 057 cm-1;蛇纹石玉具有由Si—O振动引起的特征拉曼位移678 cm-1和1 041 cm-1,由Mg—O引起的特征拉曼位移369 cm-1;石英岩玉具有由Si—O振动引起的特征拉曼位移460 cm-1;大理岩玉具有由CO2-3引起的特征拉曼位移1 080 cm-1;白色玻璃具有特征拉曼位移1 353 cm-1。根据拉曼位移的位置和强度,可无损、快速、有效地区分软玉、蛇纹石玉、石英岩玉、大理岩玉、白色玻璃。

       

      Abstract: Raman spectroscopy was used to characterize nephrite, serpentine, quartzite, marble and white glass, it is found that the characteristic Raman shifts of nephrite which are caused by Si—O vibration are 672,930, 1 057 cm-1; the characteristic Raman shifts of serpentine which are caused by Si—O vibration are 678 cm-1 and 1 041 cm-1, which are caused by Mg—O vibration is 369 cm-1; the characteristic Raman shift of quartzite which are caused by Si—O vibration is 460 cm-1; the characteristic Raman shift of marble which are caused by CO2-3 vibration is 1 080 cm-1; the characteristic Raman shift of white glass is 1 353cm-1. According to the position and intensity of each characteristic Raman shift, nephrite, serpentine, quartzite, marble and white glass can be quickly and effectively set apart without any damage to these gemstones.
