Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

open access: yesAdvanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

Mitigating Efficiency Roll‐Off in Phosphor‐Sensitized Fluorescence OLEDs via Molecular Polarity‐Based Benzofuropyridine Host Engineering

open access: yesAdvanced Optical Materials, EarlyView.
Positional isomerism in dibenzofuran‐based n‐type hosts modulates molecular polarity, charge‐transport balance, and emissive‐layer packing. The higher‐polarity BFPDB‐2 host facilitates efficient energy funneling, reduced aggregation, and preferential dipole orientation, leading to phosphor‐sensitized fluorescence OLEDs with enhanced external quantum ...

Naphthyridine‐Based Donor–Acceptor Boron Difluoride Complexes Targeting Red Emission in Organic Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, EarlyView.
Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while

Push-pull effect on the geometrical, optical and charge transfer properties of disubstituted derivatives of mer-tris(4-hydroxy-1,5-naphthyridinato) aluminum (mer-AlND3)

open access: yesOpen Chemistry, 2016
To design innovative and novel optical materials with high mobility, two kinds of disubstituted derivatives for mer-tris(4-hydroxy-1,5-naphthyridinato) aluminum (mer-AlND3) with push (EDG)–pull (EWG) substituents have been designed. The structures of mer-

Surface‐Plasmon‐Coupled Blue InGaN/GaN Micro‐LEDs with Oxide–Metal–Oxide Capping Layer Compatible to Chip Fabrication Process

open access: yesAdvanced Optical Materials, EarlyView.
A sidewall‐integrated oxide–metal–oxide architecture is demonstrated to overcome efficiency degradation in ultra‐small InGaN/GaN micro‐LEDs. Conformal Al2O3 passivation combined with plasmonic Ag nanoparticles enables localized surface plasmon–exciton coupling, converting surface‐related nonradiative losses into radiative emission.
