Stable High Power deep-UV Enhancement Cavity in Ultra High Vacuum with Fluoride Coatings [PDF]
, 2021 We demonstrate the superior performance of fluoride coated versus oxide coated mirrors in long term vacuum operation of a high power deep-ultraviolet enhancement cavity. In high vacuum ($10^{-8}$ mbar), the fluoride optics can maintain up to a record-high 10 w of stable intracavity power on one hour time scales, whereas for the oxide optics, we observe

Stopping powers of LiF thin films deposited onto self-supporting Al foils for swift protons [PDF]
, 2021 The energy losses of ~(0.273-3.334) MeV protons in Lithium Fluoride thin films deposited by vacuum evaporation onto self-supporting Al foils have been measured using the transmission method. The thicknesses of selected and used Lithium Fluoride/Al target samples were accurately determined via systematic energy loss measurements for alpha particles from

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.

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 ...

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 ...

Piezoelectric polyvinylidene fluoride-based epoxy composites produced by combined uniaxial compression and poling [PDF]
Appl. Phys. Lett. 115, 192902 (2019), 2019 We present a simple, efficient method, which combines uniaxial compression and subsequent poling, to produce piezoelectric polyvinylidene fluoride-based epoxy composites. The values of the piezoelectric factors obtained are slightly higher than those of neat piezoelectric polyvinylidene fluoride.

Prediction for new magnetoelectric fluorides [PDF]
, 2007 We use symmetry considerations in order to predict new magnetoelectric fluorides. In addition to these magnetoelectric properties, we discuss among these fluorides the ones susceptible to present multiferroic properties. We emphasize that several materials present ferromagnetic properties.

Giantically blue-shifted visible light in femtosecond mid-IR filament in fluorides [PDF]
Opt. Express 23, 29202-29210 (2015), 2015 A giant blue shift of an isolated visible band of supercontinuum was discovered and studied in the single filament regime of Mid-IR femtosecond laser pulse at powers slightly exceeding critical power for self-focusing in fluorides.

Reversible Fluorination of Graphene: towards a Two-Dimensional Wide Bandgap Semiconductor [PDF]
Phys. Rev. B 81, 205435 (2010), 2010 We report the synthesis and evidence of graphene fluoride, a two-dimensional wide bandgap semiconductor derived from graphene. Graphene fluoride exhibits hexagonal crystalline order and strongly insulating behavior with resistance exceeding 10 G$\Omega$ at room temperature.
