  • Getz, Michael; Hansen, Per-Anders Stensby; Fjellvåg, Øystein Slagtern; Ahmed, Mohammed Amin Karim; Fjellvåg, Helmer; Nilsen, Ola (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    We demonstrate controlled deposition by atomic layer deposition of YVO4:Yb3+ thin films exhibiting an intense NIR emission under UV excitation after post-deposition annealing at 1000 °C. The samples are deposited using the ...
  • Fjellvåg, Øystein Slagtern; Armstrong, Jeff; Vajeeston, Ponniah; Sjåstad, Anja Olafsen (Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)
    Hydride anion-conducting oxyhydrides have recently emerged as a brand new class of ionic conductors. Here we shed a first light onto their local vibrations, bonding mechanisms, and anion migration properties using the ...
  • Fjellvåg, Øystein Slagtern (Doctoral thesis / Doktoravhandling, 2019)
    This thesis focus on the research of the new and scarcely explored material class oxyhydrides, where the anionic lattice consists of both oxide and hydride anions. Selected oxyhydrides described by the formula La2‑xNdxLiHO3 ...
  • Fjellvåg, Øystein Slagtern; Armstrong, Jeff; Slawinski, Wojciech Andrzej; Sjåstad, Anja Olafsen (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    Oxyhydrides, in which oxide and hydride anions share the same anionic lattice, are relatively rare compounds. La2LiHO3 belongs to this family. We report the synthesis of La2LiHO3 by means of an alkali halide flux method, ...
  • Napari, M; Tarvainen, O; Kinnunen, S; Arstila, K; Julin, J; Fjellvåg, Øystein Slagtern; Weibye, Kristian; Nilsen, Ola; Sajavaara, T (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    Two distinguishable plasma modes in the O2–N2 radio frequency capacitively coupled plasma (CCP) used in remote plasma-enhanced atomic layer deposition (PEALD) were observed. Optical emission spectroscopy and spectra ...
