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

open access: yesAdvanced 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

open access: yesAdvanced 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

open access: yesAdvanced 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 ...

Plasmon‐Induced Optothermal Manipulation of Colloidal Particles and Biological Entities Resilient to Saline Environments

open access: yesAdvanced Optical Materials, EarlyView.
The particle with high surface hydrophilicity exhibits strong thermophoretic attraction, as its dense hydration layer enhances the role of interfacial water molecules in determining thermophoretic mobility over other ionic effects. This finding elucidates the mechanism underlying the robust thermophoretic accumulation of Escherichia coli in high ...

Modeling Light‐Induced Synaptic Behavior and Visual Memory of Azopolymeric Compounds

open access: yesAdvanced Optical Materials, EarlyView.
In the framework of neuromorphic hardware it is essential to predict the evolution of the internal state of the devices mimicking synaptic functionalities to perform in‐silico modeling of specific computational tasks. Here, we provide a rate‐balance equation model to describe the synaptic‐like response of light‐actuated azopolymeric compounds and ...

White Light Emission and Energy Transfer in Mixed‐Metal Europium/Terbium/Thulium Formate Metal–Organic Frameworks: Effect of Lanthanum Dilution

open access: yesAdvanced Optical Materials, EarlyView.
A series of Eu3+, Tb3+, Tm3+ and La3+ formate‐based (mixed)metal‐organic frameworks were synthesized and investigated for energy transfer and white‐light emission. Efficient Tb3+→Eu3+ transfer enabled tuneable luminescence, while Tm3+ incorporation afforded near‐white emission.
