摘要:
利用共焦显微拉曼光谱技术,以紫外激光325nm作激发光源,对黑色签字笔墨迹做了时间跨度为4年的拉曼光谱数据采集和对拉曼光谱的定量分析.结果表明:在1592 cm-1位置处的拉曼特征峰的相对强度随时间的越久远而变大.借此,可用检定材料的拉曼光谱数据与确切的不同时期的时间样本数据进行比对来判断出黑色签字笔墨迹的相对形成时间.共焦显微拉曼光谱技术为黑色签字笔墨迹的形成时间提供了一种快速、便捷、准确、无损检测的方法.
Abstract:
Th is pape r prov ides the data o f the black ro llerba ll pen s ink trace var iation in 4 successive years. Th is re search, tak ing the advantag e o f confoca lm icroRam an techno logy and the ultrav io let laser as light source, lasted 4 years running. The result show s that at the position o f 1 592 cm- 1, the ra lative integrated intensity of theRam an charac teristic peak grew along w ith the g row th o f tim e, and in accordance w ith this result, the trace form ation tim e of the b lack ro ller ball pens ink can be judg ed through the contrast of the Rom an spectra data o f the m ater ia l under compar ing w ith the sam ple tim e data of d ifferen t tim e. The result of this pape r justifies the fact that the confocal m icroRam an techno logy prov ides a quick, conven ient, accurate and nondestructive de tection m ethod for the b lack ro llerba ll pen s ink trace tes ting.
