Fluorine-containing materials offer many advantages over non-fluorine-based materials in a variety of applications.
Fluorine is a rather special element and fluorine-based materials often possess unique properties. The small size and high electronegativity of the fluorine atom, combined with the small dissociation energy of F2 (155 kJ·mol-1) are the fundamental characteristics of fluorine chemistry. Most elements react readily with fluorine, often resulting in their oxidation to the highest known oxidation states. Because of the monovalence of fluorine, fluorides at the high oxidation-state limit are often near or at the coordination limit for that element. Fluoride glasses and many other solid-state fluoride materials contain low oxidation state polymeric metal fluorides with metal centres linked through highly stable m-fluoro bridges. Many fluorine-containing materials owe their special properties to the high electronegativity of the fluoride ligand. An example are fluoride glasses with ligand-to-metal charge-transfer bands shifted well into the UV region, making the important materials for lasers, optical fibres, waveguides and optical amplifiers.
Because of the ability of fluorine to form strong and stable chemical bonds with many other elements, fluoride-based materials have found a wide usage in photonics, electronics, optoelectronics, energy storage, lithium and sodium batteries, fuel cells, supercapacitors, and membranes.
The importance of fluoride-based materials is well established and the number of applications for these materials continues to increase. This Special Issue is intended to provide an overview of the current activity in the field.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
