| 摘 要： | 采用激光显微拉曼光谱技术,选择10种不同品牌和型号的印泥(油)盖印印文的历时性样本,利用印文拉曼光谱中的1089 cm~(-1)和1235 cm~(-1)处特征峰的相对面积值(I)分析纸张、温度、热老化因素对印文形成时间的影响,探讨盖印时间与峰面积相对值(I)的关系。结果表明,I值随时间呈现规律性变化,尤其在近期内盖印印文的变化规律明显,适用于印文形成时间的鉴别,是一种准确、无损的检验方法。

| Abstract: | Objective taking advantage of micro-Raman spectroscopy technology,samples of inkpad seals were impressed with 10 different brands of ink.To analysis the factors of paper,temperature,and heat condition by relative area value(I) of characteristic peaks with 1089 cm-1 and 1235 cm-1 in Raman spectrum,in order to discuss the relation between relative area value (I) and dating of inkpad seals.The relative area value (I) showed a regular change with time,especially the stamp of impression in the near time.Micro-Raman spectroscopy is a useful method with accurate,non-destructive properties to determine the formation time of inkpad seals. |
