Method for identifying gem by using Raman spectrum

The invention discloses a method for identifying gem by using a Raman spectrum, and aims to provide the method for identifying the gem by using the Raman spectrum, with quick detection speed and an accurate detection method. The method sequentially comprises the following steps: (1) irradiating the surface of the gem by a Raman spectrum with a band of 400 to 1200cm, and detecting a ligand structure; (2) scanning again to judge whether organic pigments and organic coordinating groups CH2 and CH3 and organic group of epoxy resin exist in the gem by a Raman spectrum with a band of 2800 to 3100cm. The method belongs to the technical field of gem detection. 本发明公开了种利用拉曼光谱鉴别宝石的方法，旨在提供种检测速度快，检测方法准确的利用拉曼光谱鉴别宝石的方法，该方法依次依次包括下述步骤：1)用400～1200cm波段拉曼光谱照射宝石表面，检测配位体结构；2)再用2800～3100cm波段拉曼光谱再次扫描宝石是否存在有机色素和有机配位基团CH、CH以及环氧树脂的有机基团；属于宝石检测技术领域。
