Since long time Raman scattering revealed to be a very sensitive and easy technique to deal with the detection of mineral compounds, due to their vibrational fingerprint. However, presence of small inclusions or identification of grains with very small dimensions in rocks may still remain problematic for normal Raman detection apparatus. In this work, we propose to apply the SERS (surface-enhancement Raman scattering) effect to micro-Raman measurements for the identification and characterization of pyroxene grains embedded in polymorphous rock matrices.
长期以来，拉曼散射因其能够揭示矿物化合物的振动指纹，而成为一种非常灵敏且易于操作的矿物检测技术。然而，对于常规拉曼检测设备而言，岩石中存在的微小包裹体或尺寸极小的颗粒识别仍可能存在问题。在这项工作中，我们建议将表面增强拉曼散射（SERS）效应应用于显微拉曼测量，以识别和表征嵌入多晶岩石基质中的辉石颗粒。
