Abstract

In this paper, rare earth europium ion doped SrO-B₂O₃-Al₂O₃-SiO₂ glasses were prepared. The batches were melted under an ambient atmosphere and reheated under a reducing atmosphere. The glass after being reheated in the reducing atmosphere show long after glow phosphorescence resulted from 5d-4f transition of Eu²⁺ ion . Whereas the glasses melted under an ambient atmosphere show luminscence peaks attributed to the ⁵D_i→⁷F_j of Eu³⁺ ion.
