Crystallization in chalcogenide glasses
Friday 24 April, 09:30Passed
Glasses and Ceramics (V&C) team
Abstract
Non-oxide chalcogenide glasses possess unique combinations of optical, electric and mechanical properties which makes them ideal candidates for a wide variety of application: infrared (IR) lenses, solid electrolyte, optical fibers, photovoltaic cells, for example. By heating the glass above its glass transition temperature, crystalline particles can grow in the materials, resulting in a composite called glass-ceramic.
Her HDR presentation will begin by discussing the experience she gained prior to her position at the CNRS within the Glasses and Ceramics team, focusing in particular on the diffusion of ionic species in materials - from the origin of color in historical artefacts to the chemistry of new layered materials. She will then present the projects she is currently leading at ISCR on crystallization in chalcogenides glasses, for optical applications and solid-state electrolytes. She will conclude with an outlook on her research for the coming years, on the development of all-solid-state sodium batteries, the study of the structural evolution from glass to glass-ceramics, and finally the development of quantum dots in chalcogenide glasses.
