Abstract

The nonstoichiometric solid solutions Ba1-xRxF2+x (where R = Ce, Pr, Gd, Tb; and 0.10≤x≤0.30) are studied by Raman spectroscopy. Besides the main Raman peak, two additional bands are observed on its high-frequency side. A new interpretation for the extra-peaks, based on the cluster structure, is proposed. The observed vibrations seem to be connected with 8:12: (0, 1, 2) clusters.
