Abstract

To examine their valence state, the fluorescence of samarium phosphate glasses between 10 and 300K has been measured. The spectra do not show any obvious sign of divalent samarium ions, only trivalent samarium ion fluorescence being observed. Room temperature absorption spectra of these glasses also evidence only the absorption bands of trivalent samarium. Hence the anomalous elastic behaviour under pressure in these glasses would not seem to be due to pressure induced changes in an intermediate valence state of samarium ions, as previously inferred.
