Abstract

Using solid-state reactions, La14 – x – y Gd x Eu y (BO3)6(GeO4)2O8  solid solutions isostructural with Ln14(BO3)6(GeO4)2O8 (Ln = Pr, Nd, Sm, Eu, Gd) were prepared for the first time, and their melting points and melting behavior were established. Liquid quenching of the solid solutions was found to yield thermally stable glasses containing as much as ≃60 mol % rare-earth oxides. The composition limits of the glass-forming region were determined, and the luminescence spectra of both crystalline and glassy solid solutions were studied.
