Abstract

Borosilicate oxyfluoride glass with the composition of 50SiO₂-10B₂O₃-13Al₂O₃-14Na₂O-3ZnO-2Li₂O-8CaF₂ (mol%) doped with varied concentration of CeF₃ and/or SmF₃ were synthesized by melt-quenching method, and the corresponding transparent glass ceramics were prepared through isothermal heat treatment at 550°C for 1h. The obtained glasses and glass ceramics were characterized in structure and optical properties. The results show that SmF₃ facilitates the conversion of [AlO₆] to [AlO₄] enhancing the glass network, while CeF₃ mainly results in rupture of tetrahedral network. Doping CeF₃ may affect glass stability in a modest way, while doping SmF₃ may significantly inhibit crystallization. There is obvious energy transfer from Ce³⁺ to Sm³⁺ in a cross-relaxed manner. Rising Ce³⁺ concentration leads to the occurrence of concentration quenching whereas Sm³⁺ emission enhances with increasing concentration at higher critical level. Sitallization improves the luminous efficiency of Sm³⁺ doped glass much more than that of Ce³⁺ doped counterparts due to possible oxidation of Ce³⁺ during the heat treatment.
