摘要:
Combining a low temperature liquidizing system with a transient Raman spectroscopy, a new experimental technique is established for the first time on a two-stage light-gas gun, and it is employed to study shock-compressed fluid silane. With this experimental technique, we first obtain a Raman peak shift relating to the Si-H stretching vibration mode of molecular liquid silane under shock loading conditions. The Raman peak of 2184 cm-1 at an initial state of 0 GPa and 85 K moves to 2223.4 cm-1 at a shocked state of 10.5 GPa and 950 K, and its full width of half maximum broadens from 33 cm-1 to 118 cm-1. The shocked temperature, calculated by the thermodynamic equation of state, is well consistent with that estimated by the Doppler broadening function.
