Abstract
The evidence for the presence of Eu2+ in (Y,Eu)-Si-Al-O-N glass was studied by luminescence spectroscopy. It was observed that the (Y,Eu)-Si-Al-O-N glass shows a band centered around 450 nm, which was typical for transitions from the 5d to the 4f level of divalent Eu. The deviating behavior of the Eu-Si-Al-O-N glass with respect to mechanical properties of Ln-Si-Al-O-N glasses in which the lanthanides ion Ln was present in the trivalent state was also studied. It was found that the bandwidth of the Eu 2+ emission was about 5000-6000 cm-1 which was about the same halfwidth as observed for Eu2+ present on a single site in crystalline silicate and aluminate materials.
