The fluorescence of EuCl3 in LiCl-KCl eutectic melt according to temperature changes was investigated, and the spontaneous partial reduction of Eu3+ to Eu2+ at high temperature was confirmed by the fluorescence results. The fluorescence decreases when the temperature increases, and this was examined in detail. The studies of fluorescence provided information regarding the chemical and physical behavior of europium ions in the molten salt according to the temperature changes. It is applicable for monitoring species and concentrations and estimating the approximate chemical structure of the ions in molten salts. (C) 2010 Elsevier B.V. All rights reserved.
