Notes:
The optical-absorption spectra in Bi12SiO20 have been measured precisely at various hydrostatic pressure up to 40 kbar, and analyzed in the region below the fundamental absorption edges. It can be seen that the optical-absorption coefficients plotted semilogarithmically vary linearly with photon energy below the fundamental absorption edges at each hydrostatic pressure. The steepness of the absorption edge decreases with increasing pressure up to 10 kbar and then it shows constant value. The broad shoulders below 3.1-eV photon energy are shown, and the optical-absorption coefficients in those regions increase with increasing pressure up to 10 kbar.
