Abstract

The feasibility of employing the peak shift of the fluorescence spectrum of rhodamine 6G in an ethanol solution as a time-resolved measure of pressure for shock wave studies is demonstrated for low stresses (below 20 kbar). The results of the shock experiments are in good agreement with previous hydrostatic measurements. No effects of temperature were observed in tests to 330 K under ambient pressure, or in the comparison of static and shock data. A time resolution of approximately 80 ns was achieved with a 100 μ.m thick sample, and using a cw Argon laser as the excitation source. Higher time resolution should be possible with pulsed excitation and a thinner sample cell.
