By utilizing terahertz time-domain spectroscopy
and fourier-transform infrared spectroscopy, several kinds of traditional
Chinese pigments have been investigated covering the spectral region 0.25 THz-
7 THz. The experimental results demonstrate that all pigments studied in the
present work show a series of characteristic absorption spectra, which are
unique to the pigment species. According to the fingerprint spectra, we can
confirm that the traditional Chinese pigments have been applied to the heritage
buildings and artworks. Compared with X-ray diffraction, Raman spectroscopy and
near-infrared spectroscopic techniques, these experimental results reveal that
terahertz time-domain spectroscopy could further fill their physical
information what other techniques cannot obtain.
