Emission beyond 4 μm and mid-infrared lasing in a dysprosium-doped indium fluoride (InF3) fiber [PDF]
Optics Letters Vol. 43, Issue 8, pp. 1926-1929 (2018), 2018 Optical emission from rare-earth-doped fluoride fibers has thus far been limited to less than 4 {\mu}m. We extend emission beyond this limit by employing an indium fluoride (InF3) glass fiber as the host, which exhibits an increased infrared transparency over commonly used zirconium fluoride (ZBLAN).

Possibility to realize spin-orbit-induced correlated physics in iridium fluorides [PDF]
Phys. Rev. B 95, 235161 (2017), 2017 Recent theoretical predictions of "unprecedented proximity" of the electronic ground state of iridium fluorides to the SU(2) symmetric $j_{\mathrm{eff}}=1/2$ limit, relevant for superconductivity in iridates, motivated us to investigate their crystal and electronic structure.

Luminescent properties of Bax Mg(2−x)F4:W ceramics
Eurasian Journal of Physics and Functional Materials, 2023 Ceramics based on alkaline earth metal fluorides activated by tungsten has been obtained by radiation synthesis. The synthesis was realized by direct action on the mixture with an activator of a powerful flow of high-energy electrons without the use of ...

A Self-assembled Fluoride-Water Cyclic Cluster of $[F(H_2O)]_4^{4-}$ in a Molecular Box [PDF]
Journal of the American Chemical Society, 134, 11892 (2012), 2013 We present an unprecedented fluoride-water cyclic cluster of $[F(H_2O)]_4^{4-}$ assembled in a cuboid-shaped molecular box formed by two large macrocycles. Structural characterization reveals that the $[F(H_2O)]_4^{4-}$ is assembled by strong H-bonding interactions (OH...F = 2.684(3) to 2.724(3) {\AA}), where a fluoride anion plays the topological ...

Improved Durability of Wood Treated with Nano Metal Fluorides against Brown-Rot and White-Rot Fungi
Applied Sciences, 2022 Low-water soluble metal fluorides such as magnesium fluoride (MgF2) and calcium fluoride (CaF2) were evaluated for decay protection of wood. Initially, the biocidal efficacy of nano metal fluorides (NMFs) against wood destroying fungi was assessed with ...

Calculated high-pressure structural properties, lattice dynamics and quasi particle band structures of perovskite fluorides KZnF 3 , CsCaF 3 and BaLiF 3 [PDF]
Journal of Physics Condensed Matter 28(31):315403 (2016), 2016 A detailed study of the high-pressure structural properties, lattice dynamics and band structures of perovskite structured fluorides KZnF3, CsCaF3 and BaLiF3 has been carried out by means of density functional theory. The calculated structural properties including elastic constants and equation of state agree well with available experimental ...
