Enhancement of Eu2+ Luminescence in BaO-SiO2 Compounds Through Composition Modification

Phosphors of Eu2+-doped BaO-SiO2 compounds composed of a major BaSiO3 phase and a minor Ba2SiO4 phase were synthesized by a solid-state method at 1200?C under CO atmosphere. An enhancement of the photoluminescence of Eu2+ up to 18 times has been achieved by mixing ZnO into the composition.
