Abstract

The authenticity of calligraphy and painting is an important knowledge in the collection and research of Chinese painting and calligraphy. The identification of folk painting and calligraphy is usually conducted by experts and scholars engaged in cultural relics, archaeology, painting and calligraphy, and ancient buildings. Relying only on the identification of experience and literature and history, there are certain limitations, and it is difficult to form convincing. Spectroscopic technology mainly uses the characteristic spectral lines of molecules or atoms to judge the chemical composition and relative content of substances, so that different molecular structures of substances can be determined and distinguished; thus, it becomes an effective tool for exploring the molecular structure of substances; therefore, it has been widely used in nanomaterials, biomedicine, cultural relic identification, and other fields. Raman spectroscopy is the most common spectroscopic technique in scattering spectroscopy. When light passes through a material surface, in addition to light transmission and light absorption, light scattering can also be observed. In addition to the original incident light frequencies (Rayleigh scattering and Tyndall scattering), the scattered light also includes some new frequencies, which are called Raman scattering, and its spectrum is Raman spectrum. In this paper, Raman spectroscopy is used to study nanomaterials and calligraphy and painting, and the Raman spectra of real and fake calligraphy and painting, as well as the light absorption rate and degradation rate of nanomaterials at different temperatures, are analyzed experimentally. The results show that the Raman spectrum of the authentic calligraphy reaches the maximum when the wave number is 1000; the peak of the Raman spectrum of the authentic fresco reaches the maximum when the wave number is 1400. The average light absorption rate of nanomaterials in was 47.2%, and the average catalytic degradation rate was 53.6%; the average light absorption rate of nanomaterials was 68.9%, and the average catalytic degradation rate was 62.4%. There are obvious differences in peak shape, peak intensity, peak frequency, etc. between genuine and fake calligraphy and painting. The spectrum of genuine works has good consistency, so the authenticity of calligraphy and painting can be distinguished according to the difference between the spectrums.
