Transparent glass-ceramics

Journal of Materials Science, 1969
Glass-ceramic materials may transmit visible light if either of the following conditions are operative: (i) the crystallites of all species are much smaller than the wavelength of visible light, or (ii) the optical anisotropy (birefringence) within the crystals and refractive index difference between crystals and glass are very small.

Transparent oxyfluoride glass ceramics

Journal of Fluorine Chemistry, 2015
Abstract The present review article covers the history, featured properties and modern state of inorganic, physical and materials chemistry of transparent oxyfluoride glass ceramics. The subjects discussed include the preparation methods for these materials (e.g., synthesis from starting glass and/or amorphous matrices, devitrification, etc ...

Transparent Ferroelectric Glass-Ceramics

Ferroelectrics, 2004
In recent years, there has been a resurgence of interest in transparent ferroelectric glass-ceramics (TFGCs), which are a special class of glass-ceramic composites that combine the low cost of fabrication and forming of transparent glass with the superior nonlinear optical and electro-optical properties of ferroelectric crystals.

Transparent Oxyfluoride Glass Ceramics

MRS Bulletin, 1998
Low-phonon energy glasses are desirable hosts for rare-earth (RE) ions because they enable emission from RE energy levels that would otherwise be quenched in high-phonon energy glasses. Such emissions are of interest for fiber amplifiers operating at telecommunications wavelength band s of 1.31, 1.46, and 1.55μm, and for up-conversion lasers and three ...

Transparent glass-ceramics: crystallization mechanisms and optical properties

SPIE Newsroom, 2012
The optical performance of rare-earth-doped oxyfluoride glass-ceramics with nanocrystals smaller than 20nm suggests that these materials have a promising future in optics and photovoltaics.

Erbium partitioning in a heavily doped transparent glass ceramic

Optics Letters, 2005
An erbium-doped transparent glass ceramic, consisting of LaF3 nanocrystallites with a characteristic length of approximately 20 nm embedded in an aluminosilicate glass matrix and exhibiting infrared-to-green up-conversion, has been studied. The degree of erbium partitioning into the nanocrystallite phase was found using energy transfer coefficients ...

TRANSPARENT GLASS CERAMICS; LASER PROSPECTS

Advanced Solid State Lasers, 1985
A study of the luminescence of Cr3+ in inorganic glasses was first undertaken in order to develop a Luminescent Solar Concentrator. Broad absorption bands and near IR (vibronic) emission made the material promising for the purpose but universally low quantum efficiency (in glasses) negated that goal.
