    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.

    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.

  3. Low-Cost and Large-Area Strain Sensors Based on Plasmonic Fano Resonances

    Plasmonic Fano resonances in aluminum nanowires are utilized for strain sensing. The underlying fabrication method is suitable for large-area, high-throughput fabrication and shows a reversible, colorimetric response to elongation. The sensor can hence be remotely read out, which is an important property for applications in civil or automotive engineering.

  4. Helicity-Preserving Omnidirectional Plasmonic Mirror

    Article first published online: 29 JAN 2016 | DOI: 10.1002/adom.201500705

    A helicity preserving near-infrared mirror with a reflection efficiency over 91% for incidence angles up to 60° on any arbitrary incidence plane is realized by establishing a unified design framework of artificial electromagnetic boundaries of metasurfaces for omnidirectional polarization control. Similar efficiency and angular range of operation are observed for cross-linear polarization conversion as well.

  5. Polymeric Carbon Nitride Nanosheets/Graphene Hybrid Phototransistors with High Responsivity

    Sin Ki Lai, Chao Xie, Kar Seng Teng, Yanyong Li, Furui Tan, Feng Yan and Shu Ping Lau

    Article first published online: 28 JAN 2016 | DOI: 10.1002/adom.201500662

    A polymeric carbon nitride (g-C3N4) nanosheets/graphene hybrid phototransistor designed for the near-UV regime is reported. Efficient transfer of electrons from g-C3N4 to graphene is observed under illumination. The devices show a responsivity in the order of 103 A W−1 with a large and reproducible photocurrent. The hybrid is found stable after storing under ambient conditions for more than 130 d.
