  • Aromatic sensitizers in luminescent hybrid films 
    Hansen, Per-Anders Stensby; Svendsen, Joachim; Nesteng, Hanne Martinsen; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Atomic layer deposition offers a unique set of design possibilities due to the vast range of metal and organic precursors that can be used and combined. In this work, we have combined lanthanides with aromatic aids as ...
  • Controlling luminescence and quenching mechanisms in subnanometer multilayer structure of europium titanate thin films 
    Hansen, Per-Anders Stensby; Granerød, Cecilie Skjold; Prytz, Øystein; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    We have investigated how layered structures of TiO2 and Eu2O3 on the subnanometer scale control the optical absorption, energy transfer, emission and quenching mechanisms in sensitized lanthanide luminescence systems. By ...
  • Design of experiments approach to luminescent CaMoO4 by atomic layer deposition 
    Kvalvik, Julie Nitsche; Hansen, Per-Anders Stensby; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Atomic layer deposition (ALD) is evolving beyond binary compounds to complex oxides and doped structures, taking advantage of the nanometer precision ALD provides. In practice, the development of complex ALD-processes ...
  • Intense NIR emission in YVO4:Yb3+ thin films by atomic layer deposition 
    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 ...
  • MOF thin films with bi-aromatic linkers grown by molecular layer deposition 
    Lausund, Kristian Blindheim; Olsen, Malin Solheim; Hansen, Per-Anders Stensby; Valen, Håkon; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Thin films of metal–organic frameworks (MOFs) are promising for a wide range of applications including membranes for separations and sensor materials in microelectronics. Growth of such thin films using atomic/molecular ...
  • Molecular layer deposition of photoactive metal-naphthalene hybrid thin films 
    Rogowska, Melania; Hansen, Per-Anders Stensby; Sønsteby, Henrik Hovde; Dziadkowiec, Joanna; Valen, Håkon; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    We here report on photoactive organic–inorganic hybrid thin films prepared by the molecular layer deposition (MLD) method. The new series of hybrid films deposited using 2,6-naphthalenedicarboxylic acid (2,6-NDC) and either ...
  • Perylenes, Porphyrins, and Other Large Dye Molecules for Molecular Layer Deposition 
    Hansen, Per-Anders Stensby; Sørensen, Silje Holm; Desbois, Nicolas; Gros, Claude P.; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Abstract Molecular layer deposition (MLD) is an incredibly powerful and flexible tool for designing completely new materials with novel and unique properties. The low temperature layer‐by‐layer approach and the use of ...
  • Quinizarin: a large aromatic molecule well suited for atomic layer deposition 
    Hansen, Per-Anders Stensby; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Atomic layer deposition (ALD) is a remarkable synthesis tool due to the vast array of materials that can be deposited and the complexity of structures that can be designed. The low-temperature layer-by-layer approach even ...
  • Single-step approach to sensitized luminescence through bulk-embedded organics in crystalline fluorides 
    Hansen, Per-Anders Stensby; Zikmund, Tomas; Yu, Ting; Kvalvik, Julie Nitsche; Aarholt, Thomas; Prytz, Øystein; Meijerink, Andries; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract Luminescent materials enable warm white LEDs, molecular tagging, enhanced optoelectronics and can improve energy harvesting. With the recent development of multi-step processes like down- and upconversion ...
  • Strong self-sensitized green and NIR emission in NaYS2 doped with Pr3+ and Yb3+ by inducing Laporte allowed and charge transfer transitions 
    Hansen, Per-Anders Stensby; Kumar, Susmit; Meijerink, Andries (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Down conversion of solar UV and blue light is one of the few ways of surpassing the Shockley-Queisser limit of solar cells. One of the most efficient down conversion systems is the Pr3+ - Yb3+ lanthanide pair. However, ...
