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 (Eu_0.152Y _15.0Si_14.7Al_8.7O_54.1N _7.4). At high Eu concentrations (Eu_15.2Si _14.7Al_8.7O_54.1N_7.4) a maximum of 5 at.% could be present as Eu³⁺.
