【摘要】： 拉曼光譜作為材料指紋光譜在文物鑒定方面具有獨(dú)特的優(yōu)勢(shì)。尤其是在針對(duì)文物及珍貴藝術(shù)品,拉曼光譜的原位、無(wú)損及高靈敏的檢測(cè)特性,更是其他檢測(cè)手段無(wú)法替代的。本文利用便攜式光纖拉曼光譜儀對(duì)模擬試塊樣品、文物殘片、考古與修復(fù)現(xiàn)場(chǎng)的敦煌莫高窟壁畫(huà)進(jìn)行拉曼光譜分析與研究�；诜肿诱駝�(dòng)光譜對(duì)礦物材料的研究基礎(chǔ),對(duì)文物中的顏料分析及指認(rèn)。主要內(nèi)容及創(chuàng)新成果如下: 1.考古現(xiàn)場(chǎng)便攜式拉曼光譜儀及輔助器材的結(jié)構(gòu)設(shè)計(jì),文物拉曼光譜分析的實(shí)驗(yàn)室模擬。根據(jù)文物現(xiàn)場(chǎng)的需求與特點(diǎn),在實(shí)驗(yàn)室模擬環(huán)境下驗(yàn)證便攜式光纖拉曼檢測(cè)系統(tǒng)的適用性。在最大程度發(fā)揮其原位無(wú)損檢測(cè)特性的基礎(chǔ)上,盡可能獲得高質(zhì)量的拉曼光譜。分別通過(guò)對(duì)壓片及模擬試塊等樣品進(jìn)行光譜檢測(cè),為實(shí)際現(xiàn)場(chǎng)檢測(cè)提供方法和經(jīng)驗(yàn)。 2.根據(jù)考古現(xiàn)場(chǎng)的特殊性設(shè)計(jì)拉曼光譜檢測(cè)流程。由于考古現(xiàn)場(chǎng)可能存在的空間環(huán)境的特殊性;樣品表面特征所造成的特殊需求;以及便攜儀器在考古檢測(cè)現(xiàn)場(chǎng)的安全操作等特殊性的存在;在遵循安全性高、通用性好、操作規(guī)范適用性強(qiáng)等特點(diǎn)的基礎(chǔ)上設(shè)計(jì)拉曼光譜的檢測(cè)流程。這以流程的制定也是由于現(xiàn)今我國(guó)在文物光譜分析方面還沒(méi)有制定過(guò)細(xì)節(jié)清晰、易于操作、提高檢測(cè)安全性的操作標(biāo)準(zhǔn);而由于文物對(duì)象所具有的不可恢復(fù)的特殊性和寶貴價(jià)值,因此制定一個(gè)較為規(guī)范的文物檢測(cè)操作流程是具有重要意義的。 3.敦煌莫高窟壁畫(huà)現(xiàn)場(chǎng)與殘片的拉曼光譜檢測(cè)分析。利用優(yōu)化性能的便攜式光纖拉曼檢測(cè)系統(tǒng),以設(shè)計(jì)的具有一定規(guī)范及安全性的拉曼光譜檢測(cè)操作流程,對(duì)敦煌莫高窟石窟寺壁畫(huà)殘片及第98窟的壁畫(huà)進(jìn)行原位無(wú)損的檢測(cè)。分別利用532nm和785nm激光作為激發(fā)線的便攜式光纖拉曼光譜儀進(jìn)行數(shù)據(jù)采集,并對(duì)壁畫(huà)及殘片中礦物顏料及混合顏料給予鑒別和指認(rèn)。 4.維也納藝術(shù)館藝術(shù)品中有機(jī)染料的拉曼光譜檢測(cè)。利用拉曼和表面增強(qiáng)拉曼光譜技術(shù)對(duì)結(jié)構(gòu)相似、環(huán)境影響下易發(fā)生結(jié)構(gòu)轉(zhuǎn)化的有機(jī)染料flavanthrone和indanthrone進(jìn)行分析,通過(guò)對(duì)其表面增強(qiáng)拉曼光譜信號(hào)的分析指認(rèn),總結(jié)出了兩種染料在受污染或表觀難辨狀態(tài)下拉曼鑒別方法的表面增強(qiáng)拉曼數(shù)據(jù)特征及特征指認(rèn)官能團(tuán)信號(hào)。
[Abstract]:Raman spectroscopy as a fingerprint spectrum of materials has a unique advantage in the identification of cultural relics. Especially for cultural relics and precious works of art, Raman spectroscopy in situ, non-destructive and highly sensitive detection characteristics, but also other detection methods can not be replaced. In this paper, a portable fiber Raman spectrometer is used to analyze and study the samples of simulated samples, fragments of cultural relics and murals of Dunhuang Mogao Grottoes at the site of archaeology and restoration. Based on the molecular vibration spectrum of mineral materials, the pigment analysis and identification in cultural relics. The structure design of portable Raman spectrometer and auxiliary equipment at archaeological site, the laboratory simulation of Raman spectrum analysis of cultural relics. According to the requirements and characteristics of the cultural relics field, the applicability of the portable fiber Raman detection system is verified in the laboratory simulation environment. On the basis of maximizing its in situ nondestructive testing (NDT) properties, high quality Raman spectra are obtained as far as possible. The method and experience of practical field detection are provided by spectrum detection of pressed sheet and simulated sample. 2. According to the particularity of archaeological site, the Raman spectrum detection process was designed. Due to the particularity of the space environment that may exist at the archaeological site, the special needs caused by the surface characteristics of the sample, and the existence of the particularity of the safe operation of the portable instrument in the archaeological testing site, etc., it has high safety and good versatility. The detection flow of Raman spectrum is designed on the basis of the strong applicability of the operation standard. It is also due to the fact that there are no clear details, easy to operate and improve the safety of detection in the spectral analysis of cultural relics in our country. Due to the irrecoverable particularity and valuable value of the objects of cultural relics, it is of great significance to establish a more standardized procedure for the detection of cultural relics. Raman Spectroscopic Analysis of the scene and debris of Dunhuang Mogao Grottoes. By using a portable optical fiber Raman detection system with optimized performance, and with the designed operating flow of Raman spectrum detection with certain specification and security, the original site nondestructive inspection of the mural fragments of Dunhuang Mogao Grottoes and the murals of Grottoes 98 were carried out. The portable fiber Raman spectrometer using 532nm and 785nm laser as excitation line was used to collect data, and the mineral pigments and mixed pigments in murals and fragments were identified and identified. Raman Spectroscopy of Organic Dyes in Viennese Museum of Art. The organic dyes flavanthrone and indanthrone, which have similar structure and easy structural transformation under the influence of environment, were analyzed by Raman and surface-enhanced Raman spectroscopy, and their surface-enhanced Raman spectrum signals were identified. The surface enhanced Raman data characteristics and feature identification signals of two kinds of dye Raman identification methods in contaminated or unrecognizable state are summarized in this paper.
