Abstract

The oxidation of solid europium(II) sulphide under mild conditions has been examined by151Eu Mössbauer spectroscopy. The results show that europium(II) sulphide is remarkably stable to oxidation at 25°C and is only partially converted to Eu3+ after exposure to air for four days. Treatment in air at a temperature of 250°C for six hours induces a similar degree of oxidation. The mechanism and kinetics of oxidation of curopium(II) sulphide under mild conditions in the solid state are therefore non-trivial matters.
