- Toroidal versus Fano Resonances in High Q planar THz Metamaterials
Manoj Gupta and Ranjan Singh
Version of Record online: 26 SEP 2016 | DOI: 10.1002/adom.201600553
Mirrored Fano resonators in a planar metasurface results in an excitation of toroidal resonance that possesses higher quality factor and figure of merit values compared to Fano resonance. The toroidal coupling in Fano resonators gives rise to tightly confined loops of oscillating magnetic fields that curl around the fictitious arrow of a toroidal dipole vector in 3D space.

Upconverting cellulose nanocomposites are presented. Helicoidal co-assembly of cellulose nanocrystals with polyvinylalcohol-stabilized NaYF4:Yb,Er hexagonal nanorods yields flexible upconverting chiral photonic films that exhibit distinct optical upconversion with near-IR light and circularly polarized reflection in the visible spectrum.
- Hybrid Perovskite Thin Films as Highly Efficient Luminescent Solar Concentrators

Hybrid perovskites have proven to be a highly viable candidate for luminescent solar concentrators, achieving an optical efficiency of 29%. Unlike solar cell performance, the perovskite concentrators do not degrade rapidly, even under ambient conditions. Device performance, film morphology, and optical homogeneity show strong dependence on thin film components, signaling a large phase space remains to be investigated.
- Twist Angle and Rotation Freedom Effects on Luminescent Donor–Acceptor Materials: Crystal Structures, Photophysical Properties, and OLED Application
Jianxia Jiang, Dehua Hu, Muddasir Hanif, Xianglong Li, Shijian Su, Zengqi Xie, Linlin Liu, Shitong Zhang, Bing Yang and Yuguang Ma

The twist angle and freedom of rotation differences on the photophysical properties of donor–acceptor materials are systematically investigated by elegant molecular design. From the experimental and theoretical analysis, how these differences affect their photophysical properties is explained. A highly efficient deep-red emission organic light-emitting diode (OLED) based on these materials is also obtained with a maximum external quantum efficiency of 3.87% and Lmax = 12 000 cd m−2.
- (Al,Ga)Ox Microwire Ensembles on Si Exhibiting Luminescence over the Entire Visible Wavelength Range

The broad visible light emission observed for GaAs/(Al,Ga)Ox core/shell microwires (μ-wires) arises from recombination at F centers in the (Al,Ga)Ox shells. These μ-wires are promising structures for obtaining white-light emission on a Si platform. To realize efficient white-light emitters, it is essential to prevent the transfer of carriers to the GaAs core and the shell surface.
