Description

As the substrate of Chinese traditional painting and calligraphy, the paper and silk are susceptible to optical radiation in the museum illumination and appear mechanical damage such as brittleness, chalking, deformation, etc. However, there is no effective method now of quantitatively evaluating the mechanical damage of cultural relics caused by illumination. In this paper, Raman spectroscopy used in the analytical chemistry field was introduced into the illumination research of the cultural relics in museum. The four light sources with different center wavelengths of 450nm, 510nm, 583nm, and 650nm, which constitute the spectra of the white light-emitting-diode (LED), were used as the light sources. As experimental specimens, the paper and silk specimens were illuminated by the above light sources for half of a year. Raman spectra of specimens before and after illumination were detected. By analyzing the variations of Raman characteristic peak intensity, the relative damage coefficients of four light sources on the microscopic molecular structure of the paper and silk specimens were studied, respectively. Finally, white LED illumination, namely the spectral irradiance distribution (SPD) of white LED, for the paper and silk should be designed according to the corresponding relative damage coefficients, respectively. Simultaneously, the paper proposed a new research method of studying mechanical damage of cultural relics based on Raman spectroscopy.

Influence of Illumination on Paper and Silk used in Chinese Traditional Painting and Calligraphy Based on Raman Spectroscopy in Museum

Syracuse, NY

As the substrate of Chinese traditional painting and calligraphy, the paper and silk are susceptible to optical radiation in the museum illumination and appear mechanical damage such as brittleness, chalking, deformation, etc. However, there is no effective method now of quantitatively evaluating the mechanical damage of cultural relics caused by illumination. In this paper, Raman spectroscopy used in the analytical chemistry field was introduced into the illumination research of the cultural relics in museum. The four light sources with different center wavelengths of 450nm, 510nm, 583nm, and 650nm, which constitute the spectra of the white light-emitting-diode (LED), were used as the light sources. As experimental specimens, the paper and silk specimens were illuminated by the above light sources for half of a year. Raman spectra of specimens before and after illumination were detected. By analyzing the variations of Raman characteristic peak intensity, the relative damage coefficients of four light sources on the microscopic molecular structure of the paper and silk specimens were studied, respectively. Finally, white LED illumination, namely the spectral irradiance distribution (SPD) of white LED, for the paper and silk should be designed according to the corresponding relative damage coefficients, respectively.
