Transparent oxyfluoride glass ceramics

- Modern publications about transparent oxyfluoride glass ceramics have been reviewed.
- The present review discusses synthesis and properties of rare earth doped oxyfluoride glass ceramics.
- Spectral luminescence properties of these materials are compared with optical characteristics of glasses and single crystals.
- Microliquation, oriented attachment, rare earth allocation in fluoride nanocrystals in glass ceramics are discussed.
- X-ray diffraction, electron microscopy and other methods for determination of nanoparticle structure are analyzed.
