TLDR
The properties of an oxyfluoride glass ceramic that possesses high transparency after ceramming are described in this paper, where it is shown that a significant fraction of the rare earth dopant is preferentially partitioned into the fluoride crystal phase.Abstract:
The properties of an oxyfluoride glass ceramic that possesses high transparency after ceramming are described. Approximately 25 vol % of this material is comprised of cubic, fluoride nanocrystals and the remainder is a predominantly oxide glass. When doped with Pr+3, the fluorescence lifetime at 1300 nm is longer than in a fluorozirconate glass, suggesting that a significant fraction of the rare‐earth dopant is preferentially partitioned into the fluoride crystal phase. This material has the added advantage of being compatible with ambient air processing.read more

Nanophase glass-ceramics
TL;DR: In this article, two types of nanocrystalline glass-ceramics are studied: transparent glass and high-modulus glass with precisely engineered surfaces, and the key crystalline phases include β-quartz solid solutions, characterized by low-thermalexpansion behavior; spinel, with high hardness and elastic modulus; and mullite, which shows unique chromium-luminescence behavior.
