- Simplified Hybrid White Organic Light-Emitting Diodes with a Mixed Fluorescent Blue Emitting Layer for Exciton Managing and Lifetime Improving

A promising device structure for efficient and long-lived noninterlayer hybrid white organic light-emitting diodes (WOLEDs) is demonstrated. Two self-host blue emission materials (N,N′-di-1-naphthalenyl-N,N′-diphenyl-[1,1′:4′,1″:4″,1′″-quaterphenyl]-4,4′″-diamine) and (bis-[2-(2-hydroxyphenyl)-pyridine]beryllium) are mixed to form a bipolar mixed fluorescent blue-emitting layer for exiton managing, reducing the efficiency roll-off, improving color stability, and extending the lifetime more than four times of the hybrid WOLEDs.

A two-photon excitable temperature nanosensor is presented. Nanodots prepared from a semiconducting polymer (SCP) and a temperature-sensitive luminescent Eu(III) complex are shown to be viable materials for sensing temperature under photoexcitation at >700 nm. The SCE acts as an antenna to capture two-photon energy which then is transferred to the emitting Eu(III) complex. Both ratiometric and lifetime fluorometry can be applied.
- Powerful and Tunable THz Emitters Based on the Fe/Pt Magnetic Heterostructure

Heterostructures composed of ferromagnetic metal and nonmagnetic metal with strong spin-orbit coupling are shown to be powerful broadband THz emitters, whose field strength can be maximized by optimizing the thickness of both ferromagnetic and nonmagnetic films, and the heterostructure layers. Furthermore, the THz spectrum and its intensity are tunable by the magnetic field orientation applied on the patterned magnetic Fe/Pt heterostructures.
- Label-Free Glucose Sensing Using Chip-Scale Mid-Infrared Integrated Photonics
Pao Tai Lin, Hao-Yu Greg Lin, Zhaohong Han, Tiening Jin, Rachel Millender, Lionel C. Kimerling and Anu Agarwal

A chip-scale and label-free glucose sensor is developed by utilizing mid-IR silicon nitride waveguides. For a dry glucose covered waveguide, strong intensity attenuation is found at λ > 2.73 μm due to the OH stretches absorption. Using this characteristic spectrum, a glucose detection limit less than 0.5 ng is experimentally demonstrated.
- Accessing the High-Q Dark Plasmonic Fano Resonances in Superconductor Metasurfaces
Yogesh Kumar Srivastava, Manukumara Manjappa, Harish N. S. Krishnamoorthy and Ranjan Singh
Version of Record online: 23 AUG 2016 | DOI: 10.1002/adom.201600354
Ultrasharp Fano resonances are demonstrated in asymmetric split ring resonator arrays using a high-temperature superconductor. Ultrahigh-Q dark Fano resonances are observed at extremely low structural asymmetry regime which is inaccessible by identical high conductivity metallic structures. Significant line narrowing of superconducting Fano resonance is observed at low and high asymmetry in comparison to metal at terahertz frequencies.
