Optical glass-ceramics based on nanosized crystals of magnesium aluminate spinel doped with iron ions

Abstract

Transparent glass-ceramics of magnesium aluminum silicate system based on nanosized MgAl2O4 spinel crystals nucleated by TiO2 and doped with Fe2O3 were developed. Their structure and spectroscopic properties were studied. The glass-ceramics are important as reference samples in development of saturable absorbers in the short-wave infrared spectral range (2-3 μm).

Synthesis, structure and spectroscopy of Fe2+:MgAl2O4 transparent ceramics and glass-ceramics

“…Though there exist studies on the iron-doped GCs of the magnesium aluminosilicate system, they aim to develop opaque GCs based of iron-doped cordierite [55][56][57]. The preliminary results on the development of Fe:MgAl2O4-based transparent glass-ceramics were first published in [58,59].…”
