黄色葡萄石的光谱学特征研究
|
摘要
利用傅里叶变换红外光谱仪、拉曼光谱仪和紫外可见光谱仪等测试分析手段,并结合偏光显微镜及常规宝石学方法,对黄色葡萄石样品进行了系统的测试研究。结果表明,黄色葡萄石具有典型的显微交织结构。红外吸收光谱和拉曼光谱显示了硅氧官能团的振动在900-1100cm~(-1)和400~800cm~(-1)波段产生特征吸收峰,同时OH~-的振动产生了3495cm~(-1)红外吸收峰和320cm~(-1)、390cm~(-1)拉曼吸收峰。紫外可见光谱显示,葡萄石具有430nm和580nm的吸收带,推断其黄色调是由Fe~(3+)致色形成的。
In this paper, we researched the spectral characteristics of yellow prehnite by using Fourie transform infrared spectroscopy, Raman spectroscopy and UV-Vis absorption spectroscopy, combined with polarizing microscope and common gemmogical methods. The prehnite shows typical micro-intertexture structure. Si-O functions caused characteristic infrared absorption peaks and Raman spectra between 900~1100 cm~(-1) and400~800 cm~(-1). While OH~- caused 3495 cm~(-1) infrared absorption peaks and 320 cm~(-1), 390 cm~(-1) Raman spectra. In the UV-Vis absorption spectra, yellow prehnite shows 430 nm and 580 nm bands, so it is inferred that the yellow prehnite may be caused by Fe~(3+).
