Abstract

•Sr4Al14O25:Eu2+,Dy3+ microparticles-containing glasses were successfully prepared.•Changes in the melting procedure modify the intensity of the persistent luminescence.•Oxidation of the Eu2+ ions into Eu3+ ions during glass melting.•Possible to tailor the persistent luminescence properties of the glasses.

In this paper, we discuss the impact of the temperature and the duration of the melting on the persistent luminescence properties of phosphate glasses within the P2O5–Na2O–CaO and P2O5–Na2O–SrO systems prepared using a standard melting process in normal atmosphere by adding Sr4Al14O25:Eu2+,Dy3+ microparticles in the glass batch before melting. Glasses with persistent luminescence properties can be successfully prepared if the melting conditions are carefully controlled.
