Abstract

In this work the fluorescence spectrum of Eu^2- doped CsCl single crystals has been systematically investigated for different annealing treatments. The quenched samples present an emission band peaking at 22700 cm_-1 due to Eu-vacancy complexes and two additional emissions at 22040 and 20524 cm^-1, which are related to small europium aggregates. Thermal annealing of the samples induces the formation of Eu precipitates with a platelet-like structure along {220} crystal planes, giving rise to an emission band at 23120 cm^-1. A first result of an Eu^2- induced aggregation by ultraviolet laser irradiation is presented.
