Abstract

A kinetic-cooling effect in the liquid phase has been observed by the use of pulsed optoacoustic spectroscopy. The magnitude of the optoacoustic signal in an aqueous Eu31 solution, as measured from the absorption of pulsed light, was found to decrease when the excitation-laser wavelength was tuned to the transition from the thermally excited ⁷F₁ state to the upper electronic ⁵D₀ state of Eu³⁺ ion. This anomalous optoacoustic phenomenon is attributed to the kinetic-cooling effect.
