Abstract

Abstract A crystallization study of the TeO 2 –InF 3 glass system shows that the specific glass composition 75TeO 2 –25InF 3 stabilizes a novel cubic anti‐glass phase within the glass matrix upon heat treatment. This peculiar crystalline phase also called “glass of anions” exhibits an interesting order/disorder coexistence, that is, a long‐range cation order but with a highly disordered anion sublattice. The thermal properties, structure and microstructure of the parent glass and corresponding glass‐ceramics have been studied. Finally, the luminescence of Yb 3+ ‐doped glass‐ceramics has been characterized, which confirmed the presence of the disordered anti‐glass phase.
