研究目的
Investigating the application of UV-Vis reflectance spectroscopy and microspectrofluorimetry as non-invasive methods for the study of cultural heritage materials.
研究成果
UV-Vis reflectance spectroscopy and microspectrofluorimetry are powerful non-invasive techniques for the study of cultural heritage materials, offering unique advantages in the identification of colourants and the characterization of artworks. However, their limitations highlight the need for complementary analytical techniques in certain cases.
研究不足
The spectral responses can be poor in artworks or samples with irregular surfaces or that are partially transparent; it is generally not possible to discriminate colourants having similar absorption features. In such cases, the complementary use of other analytical techniques is mandatory.
1：Experimental Design and Method Selection:
The study discusses the use of UV-Vis reflectance spectroscopy and microspectrofluorimetry for non-invasive analysis of cultural heritage materials.
2：Sample Selection and Data Sources:
Various cultural heritage materials including paintings, manuscripts, textiles, carpets, tapestries, glass, metals, and minerals were analyzed.
3：List of Experimental Equipment and Materials:
Portable FORS systems, microspectrofluorimeters, and reference standards like barium sulphate plates or fluoropolymer targets were used.
4：Experimental Procedures and Operational Workflow:
Reflectance spectra were acquired in situ using portable devices, and fluorescence measurements were made with spectrofluorimeters hyphened to confocal microscopes.
5：Data Analysis Methods:
Reflectance spectra were analyzed for identification of materials, and fluorescence spectra were used for high sensitivity and selectivity in identifying dyes and lake pigments.
