Preparation and luminescence properties of Eu2+-doped BaSi2O5 glass-ceramics

► Eu2+:BaSi2O5 glass-ceramics was prepared by crystallizing Eu3+:barium-silicate glass. ► Static and time-resolved luminescence measurements conducted. ► Eu2+ formed and incorporated into BaSi2O5 crystallites. ► Eu2+ luminescence increases dramatically if monoclinic BaSi2O5 is formed. ► Eu3+ ions remain in amorphous phase.
