    The bending photoluminescence (BPL) and surface photovoltaic effect of a thin multilayer InSe 2D microplate crystal are demonstrated. The BPL result shows an enhancement in light intensity (×6) with respect to that of the other flat PL measurement for InSe. A small area of In-InSe Schottky solar cell is also tested. The testing result shows a photovoltage of V ≈ 24 mV was generated from the Schottky solar cell under the illumination of Hg lamp.

  2. Shape Memory: Random Lasing in Novel Dye-Doped White Paints with Shape Memory (Advanced Optical Materials 8/2015) (page 1079)

    Shape-memory composites may be used as advanced photonic white paints to manipulate the transport of light. On page 1080, M. C. Serrano, A. Blanco, and co-workers show how they can perform as shape-configurable active media when doped with an organic dye, able to sustain non-resonant feedback random lasing. Photoluminescence may be used to monitor the heat-induced shape-restoration process, as shown on successive steps in this artistic composition.

  3. Metamaterials: A Metamaterial Emitter for Highly Efficient Radiative Cooling (Advanced Optical Materials 8/2015) (page 980)

    Anisotropic metamaterial emitters can serve a key role in highly efficient radiative cooling. Described by M. Gu and co-workers on page 1047, they are designed to selectively radiate within the atmospheric transparency window and minimize absorption of atmospheric radiation outside the window. Using these unique radiative properties, a device realized with these artificial emitters has the ability to cool down 12 °C below the ambient temperature.

  4. Spin Hall Effect: Photonic Spin Hall Effect with Nearly 100% Efficiency (Advanced Optical Materials 8/2015) (page 1126)

    Weijie Luo, Shiyi Xiao, Qiong He, Shulin Sun and Lei Zhou

    Article first published online: 25 AUG 2015 | DOI: 10.1002/adom.201570051

    The giant photonic spin Hall effect is experimentally demonstrated with nearly 100% efficiency on page 1102 by S. Sun, L. Zhou, and co-workers (Fudan University, China). When linearly polarized light strikes at certain reflective Pancharatnam–Berry metasurfaces designed based on a general criterion, the reflected wave splits into two spatially separated beams with different circular polarizations. This finding will stimulate many interesting applications based on the high-efficiency manipulation of the spin of light.
