Fig. 6From: Combined photoluminescence and Raman microscopy for the identification of modern pigments: explanatory examples on cross-sections from Russian avant-garde paintingsLeft panel: Analysis points investigated through Raman microscopy (highlighted as black circles over the colour picture of the sample). Right panel: Raman spectra of the samples L6. Layer 1 shows the presence of Cinnabar (250(vs), 280(sh-w) and 343(m) cm−1). Layer 2 shows the peak of Hydrocerussite (1050 cm−1), Gypsum (1000 cm−1) and Zinc Oxide (438 cm−1). In addition, a residue of Cinnabar (250(s) cm−1) is detected in Layer 2Back to article page
