Abstract

Electronic absorption spectra of trivalent neodymium in LiCl-KCl eutectic, NaCl-2CsCl eutectic, CaCl2, LiCl, CsCl and mixtures of these at various temperatures were measured, and the variation of the absorption bands, 4G5/2, 2G7/24I9/2, were carefully analyzed. The dependence of their molar absorptivity, oscillator strength, and the degree of the energy splitting on temperature and melt composition were determined. As a result, it was suggested that the NdCl6 3- complex keeps its octahedral symmetry in the NaCl-2CsCl eutectic, while this symmetry is more distorted in LiCl and CaCl2. Based on these data, the chemical status of NdCl 6 3- complex in molten chlorides was discussed.
