  1. Cloaking Contacts on Large-Area Organic Light-Emitting Diodes

    Frederik Mayer, Robert Schittny, Amos Egel, Andreas Niemeyer, Jan Preinfalk, Ulrich Lemmer and Martin Wegener

    Metal contact grids on top of organic light-emitting diodes are often necessary electrically, but they cast unwanted optical shadows. Invisibility cloaks for diffuse light can reduce these shadows and thereby homogenize the light emission. Optimized structures lead to only small reduction of the overall light emission. Monte Carlo ray-tracing simulations and model experiments are in good agreement.

  2. Ultrathin Second-Harmonic Metasurfaces with Record-High Nonlinear Optical Response

    Jongwon Lee, Nishant Nookala, J. Sebastian Gomez-Diaz, Mykhailo Tymchenko, Frederic Demmerle, Gerhard Boehm, Markus-Christian Amann, Andrea Alù and Mikhail A. Belkin

    Ultrathin metasurfaces with record-high nonlinear optical response of 1.2 × 106 pm V−1 for second harmonic generation are experimentally demonstrated in the mid-infrared spectral range. A second harmonic power conversion efficiency of 0.075% is achieved in a 400-nm-thick (λ/25) metasurface at a pump intensity of only 15 kW cm−2.

  3. Lithography-Free Large-Area Metamaterials for Stable Thermophotovoltaic Energy Conversion

    Zachary J. Coppens, Ivan I. Kravchenko and Jason G. Valentine

    A large-area metamaterial thermal emitter is fabricated using facile, lithography-free techniques. The device is composed of conductive oxides, refractory ceramics, and noble metals and shows stable, selective emission after exposure to 1173 K for 22 h in oxidizing and inert atmospheres. The results indicate that the metamaterial can be used to achieve high-performance thermophotovoltaic devices for applications such as portable power generation.

  4. Towards Bright and Fast Lu3Al5O12:Ce,Mg Optical Ceramics Scintillators

    Shuping Liu, Jiri A. Mares, Xiqi Feng, Anna Vedda, Mauro Fasoli, Yun Shi, Huamin Kou, Alena Beitlerova, Lexiang Wu, Carmelo D'Ambrosio, Yubai Pan and Martin Nikl

    Article first published online: 3 FEB 2016 | DOI: 10.1002/adom.201500691

    The synergistic effect of Mg co-doping and air-annealing on LuAG:Ce,Mg ceramicsis studied. Significantly improved scintillation properties and reduced afterglow intensities are obtained. The relation between Mg content and spectral properties is discussed and correlated with the physical mechanisms occuring in the scintillation process.

  5. In Situ Surface Assembly Derived Ultralow Refractive Index MgF2–SiO2 Hybrid Film for Tri-Layer Broadband Antireflective Coating

    Xinmin Cui, Ruimin Ding, Mengchao Wang, Cong Zhang, Ce Zhang, Jing Zhang and Yao Xu

    The MgF2–SiO2 coatings with ultralow refractive index of 1.12 and tunable refractive index of 1.20–1.44 are prepared by a facile sol–gel procedure without post-treatment. Then, a tri-layer broadband AR coating with refractive index model of 1.12/1.26/1.36 is realized with excellent transmittance of nearly 100% at 351, 527, and 1053 nm simultaneously.
