Abstract
The thermal decomposition of hydrated europium sulfate was monitored by high resolution photoluminescence studies of the decomposition products. By application of the luminescence method, information can be gleaned from the fine structure within the europium(III) bands regarding the number of europium (III) species existing in the sample. In addition, some idea of the site symmetry of the emitting europium(III) species can be deduced from a detailed analysis of the spectra. Examination of the luminescence spectra revealed that dehydration of the europium(III) sulfate yields a multitude of hydrated intermediates, and these eventually form a well-defined anhydrous sulfate. Our data indicate the presence of a hitherto unsuspected intermediate Eu 2O(SO 4) 2 in the decomposition of the anhydrous Eu 2(SO 4) 3 to a well-defined Eu 2O 2SO 4 end product.
