Fig. 1. Shock-pressure dependence of the optical absorption spectra for CalrO₃-Al₂O₃ with eight crystallographic orientations (a, c, d, r, n, s, g and m indicate a, c, d, r, n, s, g and m orientations, respectively. The calculated data have been corrected by shock temperature): (a) Data calculated with higher defective concentration model at 131.2 GPa and 255 GPa (the inserted figure shows perfect-crystal data); (b) data calculated with lower defective concentration model at 131.2 GPa and 255 GPa.

Fig. 2. Pressure dependence of the optical absorption spectra for perfect CalrO₃-Al₂O₃ with eight crystallographic orientations (a, c, d, r, n, s, g and m indicate a, c, d, r, n, s, g and m orientations, respectively).

Fig. 3. Effects of the shock temperature and vacancy point defect on the high-pressure optical absorption spectra for CalrO₃-Al₂O₃ with eight crystallographic orientations (a, c, d, r, n, s, g and m indicate a, c, d, r, n, s, g and m orientations, respectively).

Fig. 4. The calculated optical absorption spectra and the measured extinction coefficients for CalrO₃-Al₂O₃ with two crystallographic orientations at shock pressure of 255 GPa (c and r indicate c and r orientations, respectively. The calculated data have been corrected by shock temperature).
