Abstract

Cubic (x = 0.3) and rhombohedral (x = 0.2) phases have been prepared in the solid solution (Bi2O3)1-x(Eu2O3)x. The cubic material transformed to the rhombohedral form when subjected to a pressure of 4 GPa at a temperature of 873 K; at 4 GPa and 1073 K the transformation was to a phase of apparently monoclinic symmetry. 151Eu Mössbauer spectroscopy has been used to study all three forms of (Bi2O3)0.7(Eu2O3)0.3 in order to estimate the extent of anion-vacancy ordering in the solid solution. The Mössbauer linewidth from all samples is lower than that measured for CEu2O3, suggesting that the Eu atoms in these compounds have a single, well-defined, local environment.
