We cordially invite you to contribute to this Special Issue on ion exchange in glasses and crystals. As you know, the ion-exchange reaction may be defined, according to Britannica.com, as any of a class of chemical reactions between two substances (each consisting of positively and negatively charged species called ions) that involves an exchange of one or more ionic components. Since its first observation in 1850, ion-exchange has become a fundamental process in many applications involving treatment and purification of water and, more generally, in catalysis, chromatography, food industry, pharmaceutical industry. One of the first relevant applications of ion-exchange, however, was in the industry of glass, with the surface tempering of glass produced by a K+-Na+ ion exchange; nowadays, ion exchange-strengthened glass is present in many smartphones. One century ago, in 1918, Schott researchers observed that ion exchange also produced an increase of the refractive index in the diffused layers.
In a century, the applications of the ion-exchange (IOX) process in glasses and crystals have been very many, allowing us the production of graded-index optical components and waveguides, of passive and active devices. Ion-exchange in glass and ferroelectric crystals, such as lithium niobate, has been fundamental for the development of many linear and nonlinear integrated optical devices.
This Special Issue aims at producing an updated overview of this wide field, reviewing the current state-of-the-art and presenting perspectives of further development. Contributions are sought related to fundamental aspects, design and fabrication processes, characterization, and, eventually, applications of ion-exchange technology in different types of glasses and crystals. Even if the core of this Special Issue will presumably be concerned with photonic applications, other uses of ion-exchange in glasses and crystals will also be of interest.
Original research papers in all areas of theory, fabrication, characterization and applications of ion-exchange in glasses, glass-ceramics, and crystals will be considered, including but not limited to:
- Thermal and field-assisted diffusion processes
- Ion-exchange processes in oxide glasses, chalcogenide glasses, other glasses
- Ion-exchange in glass-ceramics
- Ion-exchange processes in ferroelectric and other crystals
- Ion exchange in semiconductors
- Nanomaterials synthesis by ion-exchange techniques
- Modeling of ion-exchange process
- Graded-index structures by ion-exchange (microlenses, optical gratings, GRIN lenses, mode converters, etc.)
- Ion-exchange based integrated optics (waveguides, components, modulators, nonlinear devices, amplifiers and lasers, sensors, etc.)
- Other applications
Review articles on any aspect of ion-exchange in glasses and crystals will be considered as well. Prospective authors are encouraged to contact the Guest Editors to submit their proposal.
