Ja. Zuo et al., Raman microscopy study of the pigments on the ancient wall painting from the large grave in Wanzhang (Hebel, China), SPECT LETT, 32(5), 1999, pp. 841-850
Fragments of the ancient wall painting (c. 550 - 580 AD) from the archaeolo
gical site of Wanzhang (Heibei, China) were analyzed by Raman Microscopy. T
he pigments with different colors were identified by Raman Microscopy, whic
h are respectively cinnabar, goethite, carbon black and calcite doped with
other metal atoms.
