摘要：文物保护与考古工作者最为关心的是从文物中无损提取各种有用信息,了解文物老化状况,以便采取合适的保护措施。文章选用桑蚕丝、书画和彩绘文物常用材料印章、胭脂、朱砂、朱膘国画颜料为样品,采用便携式拉曼光谱仪检测样品在紫外光辐照前后光谱变化,进行文物光老化研究。结果表明,在360 nm波长,照度0.68 W.m-2的紫外光下,蚕丝样品47 h发生明显降解现象;便携式拉曼光谱仪采集的光谱能清晰鉴别出印章印泥种类和来源,灵敏检测出印泥和其他国画颜料经163 h紫外辐照后发生氧化分解及颜料分子结构的变化。该工作为文物现场检测、研究实际环境因素对文物影响作用,为研究文物衰变规律提供了一种便捷检测手段。
Identification and characterization of materials used in cultural heritage and conservation can provide important information for dating,authentication and deteriorating situation in general.How to extract useful information from these materials in-situ is one of the main concerns.Application of mobile Raman spectroscopy for this purpose has great attentions for scientists and conservators.The present paper aims to investigate the mobile Raman spectroscopy in studying the effect of UV light on the deterioration of silk,seal ink and Chinese traditional colorants such as kermes,vermillion and zhubiao,which is commonly appeared on painted works of art,and the silk sample is also often used as an consolidant for repairing destroyed textile objects.Spectra were recorded from predefined regions on the samples before and after ultraviolet radiation with 360 nm wavelength and 0.68 W·m-2 intensity.The result revealed obvious effects of ultraviolet radiation on the materials simulated in this research.The original kind of seal ink has been clearly identified.The changes in spectra of all samples with and without UV radiation were further distinguished and studied. The result will assist for scientists and conservators to determine the safe treatments and suitable enviro nmental condition for storage,display and transport.The result will also help for studying mechanism of deterioration of museum objects influenced by enviro nmental factors.The mobile Raman spectroscopy showed a suitable and convenient means for in-situ non-destructive detection and study of deterioration in practical conditions.
