Nonconventional Li₂O–SrO–Al₂O₃ glass preparable through melt-quenching: A preliminary study

Abstract

Basically, nonconventional aluminate glass is hardly prepared by melt-quenching technique. In this study, we could obtain the 15Li₂O–55SrO–30Al₂O₃ glass through melt-quenching, and suggested the Li₂O–SrO–Al₂O₃ system as new glass-forming system. The studied glass was demonstrated to have a similar structure to binary SrO–Al₂O₃ glasses so far. In addition, we found a restrictive glass-forming region in the Li₂O–SrO–Al₂O₃ system. Furthermore, we observed the photoluminescent (PL) and PL excitation spectra, which were attributed to f–f transitions, in the resulting glass-ceramics (GCs) doped with Eu³⁺, suggesting that the GCs in Li₂O–SrO–Al₂O₃ system have a potential for phosphor host material.
