  1. Selectively Patterning Polymer Opal Films via Microimprint Lithography

    Tao Ding, Qibin Zhao, Stoyan K. Smoukov and Jeremy J. Baumberg

    Article first published online: 1 SEP 2014 | DOI: 10.1002/adom.201400327

    Microimprint lithography applied to polymer photonic crystals made of core–shell particles generates striking patterns of local structural color. Because of the elastic shells, the hard spherical cores are rearranged under different pressures and shearing forces, providing a way to produce structural color patterns that can be actively tuned.

  2. Transverse Electric Mode for Near-Field Radiative Heat Transfer in Graphene–Metamaterial Systems

    D. Drosdoff, A. D. Phan and L. M. Woods

    Article first published online: 28 AUG 2014 | DOI: 10.1002/adom.201400275

    Heat transfer via radiation can be enhanced across short distances when the system supports resonant tunneling of surface electromagnetic modes. For certain metamaterials, the transverse electric mode is available. Such magnetically active artificial composites can facilitate coupling with the transverse electric mode of graphene. Graphene transverse electric or magnetic channels for the near-field radiation can be emphasized or inhibited by design.

  3. Gas Sensors: CdS/ZnO Core/Shell Nanowire-Built Films for Enhanced Photodetecting and Optoelectronic Gas-Sensing Applications (Advanced Optical Materials 8/2014) (page 737)

    Zheng Yang, Linjuan Guo, Baiyi Zu, Yanan Guo, Tao Xu and Xincun Dou

    Article first published online: 22 AUG 2014 | DOI: 10.1002/adom.201470050

    A photodetector and a room temperature optoelectronic gas sensor with excellent performance are realized by B. Y. Zu, X. C. Dou, and co-workers, who hydrothermally synthesize CdS/ZnO core/shell nanowires using a two-step process on page 738. Remarkable improvement in the gas-sensing performance under light illumination is attributed to the huge increase in photoelectron density in ZnO shell and the effective inhibition of the recombination of photogenerated electrons and holes.

  5. Plasmonics: Nanoscale Imaging and Spectroscopy of Plasmonic Modes with the PTIR Technique (Advanced Optical Materials 8/2014) (page 698)

    Aaron M. Katzenmeyer, Jungseok Chae, Richard Kasica, Glenn Holland, Basudev Lahiri and Andrea Centrone

    Article first published online: 22 AUG 2014 | DOI: 10.1002/adom.201470047

    An atomic force microscopy (AFM) tip is used to provide local absorption maps and spectra of plasmonic resonators in the mid-IR. On page 718, A. Centrone and co-workers use photothermally induced resonance (PTIR) to combine the lateral resolution of AFM, enabling the measurement of light absorption at a length scale several times smaller than the light diffraction limit. Since the PTIR signal is not affected by scattering, PTIR spectra are free of Fano spectral distortions typically observed in the far-field.
