First Identification of Rare-Earth Oxide Nucleation in Chalcogenide Glasses and Implications for Fabrication of Mid-Infrared Active Fibers. Journal of the American Ceramic Society, 97(2), 432-441. https://doi.org/10.1111/jace.12732

Gallium (Ga) helps solubilize rare-earth ions in chalcogenide glasses, but has been found to form the dominant crystallizing selenide phase in bulk glass in our previous work. Here, the crystallization behavior is compared of as-annealed 0–3000 ppmw...
