Abstract

When Eu³⁺ ions in aqueous solution are excited from ⁷F₁ state to ⁵D₀ state with a pulsed dye laser, the population of Eu³⁺ ions in the ⁷F₁ state decreases temporarily due to the slow decay of the ⁵D₀ state. The magnitude of transient photoacoustic signal from absorption of light by water and Eu³⁺ ions was found to decrease when the dye laser wavelength was tuned to the transition. This anomalous photoacoustic effect is attributed to the fast thermal equilibrium between 'cold' Eu³⁺ ions and ambient water molecules.
