We describe a fluorescence probe thermometer for measuring shock heating directly in transparent solvents. As a demonstration of this scheme, the temperature of shocked water was measured in a previously inaccessible pressure regime, 0–9 kbar, by observing the fluorescence enhancement from a fluorescein dye additive following 527-nm excitation and laser driven shock loading. A ring-up shock temperature increase of 33 °C was observed at 8.4 kbar with an accuracy of ±4 °C.
