Reconnaissance Peptide Labeling Grain Boundary of Chemically Grown MoS2 Polycrystalline Monolayer

Advanced Materials Technologies, EarlyView.
Self‐assembled peptides on substrates, through adsorption and aggregation, offer an alternative way to label grain boundaries in chemically grown single‐layer polycrystalline MoS2. During an early nucleation step, peptides preferentially bind to grain boundaries.

Understanding Interfacial Photoswitching Mechanisms in Atomically‐Thin TMD‐Spiropyran Hybrids

Advanced Materials Technologies, EarlyView.
Photochromic molecules can effectively modulate the optoelectronic properties of atomically thin transition metal dichalcogenide semiconductors. Spiropyran that switches its chemical configuration upon alternating UV and visible irradiation enables light‐programmable optoelectronic devices.

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

Advanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Ultrathin and Flexible Organic Light‐Addressable Potentiometric Sensors

Advanced Materials Technologies, EarlyView.
The first ultrathin, fully organic, and flexible light‐addressable potentiometric sensor (LAPS) is demonstrated. With a thickness of only 2.3–2.9 µm, this standalone film offers sensitivity to electrolyte potential and stable performance for over 170 days.

Printed SWCNT‐Based p–n Junction Thin‐Film Near‐Infrared Photoresistors Enabled by a Sustainable Furan‐Derived π‐Conjugated Polymer

Advanced Materials Technologies, EarlyView.
A sustainable polymer–carbon nanotube bilayer enables efficient near‐infrared photodetection in a simple lateral planar p–n junction thin‐film architecture. Thermal side‐chain cleavage enhances interfacial coupling, shifts the dominant photoresponse from 800 to 1000 nm, and substantially improves device performance.

Peculiarities of electrooptical characteristics of gallium phosphide light-emitting diodes in high injection level conditions

Ядерна фізика та енергетика, 2015
Electroluminescence of green N-doped gallium phosphide light-emitting diodes was studied. The negative differential resistance region in the current-voltage characteristics was found at low temperature (Т ≤ 90 К).

The Role of Charge Transfer and Linker States in the Magnetoluminescence of a Diradical With Two Spatially Proximate Triarylmethyl Units

Advanced Optical Materials, EarlyView.
Magnetoluminescent (ML) diradicals exhibit field‐dependent emission due to magnetic field‐dependent spin state populations and spin‐dependent emission properties. In this work, quantum chemical calculations applied to the first reported ML diradical provide evidence of the different deactivation pathways of the excited singlet and triplet states and ...

High Efficiency 3‐Tandem Top Emitting Pure‐Blue OLEDs Beyond the BT.2020 Blue Standard

Advanced Optical Materials, EarlyView.
We report a high‐efficiency ultrapure‐blue 3‐tandem TEOLED through synergistic optimization of a narrowband MR‐TADF emitter, Purcell‐based cavity design, and pure Ag cathode/CPL structure. The optimized device achieves 463 nm emission, an ultranarrow FWHM of 10 nm, CIE y of 0.040, and a blue index of 1,596 cd/A/y, surpassing the BT.2020 blue standard ...

Engineering Energy Harvesting Pathways in Mn‐Yb‐Doped Perovskite Nanocrystals

Advanced Optical Materials, EarlyView.
Mn‐Yb codoping in metal halide perovskite nanocrystals establishes dual‐channel energy reservoirs that capture charge carriers and drip‐feed them back to the host on millisecond timescales. This synergistic recycling mechanism overcomes prompt nanosecond recombination limitations, enabling an eight‐fold enhancement in photocatalytic CO2​ reduction ...
