Curcuminoid Derivatives with a Donor‐Acceptor‐Donor Architecture: an Outstanding Platform for Highly‐Efficient Near‐Infrared Electroluminescence and Amplified Spontaneous Emission

Advanced Optical Materials, EarlyView.
Curcuminoid boron difluoride dyes containing triphenylamine units are prepared and their photophysical and electrochemical properties are investigated. These new light‐emitting dyes are used in organic light‐emitting diodes (OLEDs) emitting at 800 nm with 1% external quantum efficiency, and show low threshold amplified spontaneous emission in thin ...

Demonstration of a Graphene Adjustable‐Barriers Phototransistor with Tunable Ultra‐High Responsivity

Advanced Optical Materials, EarlyView.
A novel graphene‐based phototransistor with a tunable ultra‐high responsivity of 1.7 x 107 AW−1 has been demonstrated. Due to the selected material combination of amorphous silicon, graphene and n‐germanium, the device is potentially capable of dual‐band detection in the VIS‐IR range.

Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies

Advanced Optical Materials, EarlyView.
A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.

Optical Self‐Tuning of Ferroelectric Metasurfaces Infiltrated with Nematic Liquid Crystals via Photovoltaic Effect

Advanced Optical Materials, EarlyView.
A novel scheme is introduced to achieve optical self‐tuning in ferroelectric lithium niobate (LN) metasurfaces equipped with a thin film of liquid crystals (LCs). The resonant optical field distributions inside the meta‐atoms can induce a photovoltaic (PV) field, which reorients the surrounding LCs.
