Abstract
Two-photon absorption (TPA) spectroscopy is used to study the aggregation kinetics of ${\mathrm{Eu}}^{2+}$ in KCl single crystals at two different annealing temperatures. The sharp f\ensuremath{\rightarrow}f transitions allow an easy observation of different precipitated phases of ${\mathrm{Eu}}^{2+}$ as opposed to the one-photon absorption and fluorescence of the 4${f}^{6}$5d transition, where overlapping bands make the analysis of the aggregated phases difficult. Since it is possible to measure the precipitated phases simultaneously, this technique is better than previous techniques used to study the first aggregation products and that detect only the impurity-vacancy (I-V) dipole concentration. The order of the kinetics equation has been established for two types of clusters. We also report the TPA spectrum of the Suzuki phase.
