Abstract

This paper describes a method to determine the oxidation state of europium by means of magnetic measurements. The feasibility of this method is demonstrated using Eu-doped Y¿Si¿Al¿O¿N glasses as a model system. Magnetic measurements at (Eu,Y)¿Si¿Al¿O¿N glasses show that Eu is completely present as divalent ion for low Eu concentrations (Eu0.152Y15.0Si14.7Al8.7O54.1N7.4). At high Eu concentrations (Eu15.2Si14.7Al8.7O54.1N7.4) a maximum of 5 at.% could be present as Eu3+.
