Abstract

The Eu3+-activated strontium aluminate-based Sr3Al2O6:Eu3+,Ho3+, Sr2.99Ba0.01Al2O6:Eu3+,Ho3+ and Sr2.99Mg0.01Al2O6:Eu3+,Ho3+ phosphor systems were prepared by the solid-state reaction method under open atmosphere. DTA/TG analysis was conducted to obtain the thermal behaviours of the phosphors. Depending on the thermal analysis results, the heat treatments were carried out and the obtained single phase formations were characterised by X-ray diffraction. The effects of Ba2+ and Mg2+, which were individually added as trace amounts, and also of the same activator (Eu3+) and co-dopant (Ho3+) that were used for all host lattices, on the photoluminescence and phase formation properties of the hosts were investigated.
