Intrinsically‐Stretchable and Patternable Quantum Dot Color Conversion Layers for Stretchable Displays in Robotic Skin and Wearable Electronics

open access: yesAdvanced Materials, EarlyView.
Intrinsically‐stretchable, heavy‐metal‐free quantum dot color conversion layers are produced via a versatile crosslinking strategy. The color conversion layers exhibit minimal backlight leakage under mechanical strain, support high‐resolution patterning, and integrate seamlessly with micro‐light‐emitting diodes. Their incorporation in haptic‐responsive

Enhanced Performance of Inkjet Printed Red Quantum Dot Light‐Emitting Diodes Influenced by ETL Uniformity with Solvent Systems

open access: yesAdvanced Optical Materials, EarlyView.
This study investigates the impact of solvent systems on the uniformity of the ZnO electron transport layer (ETL) in inkjet‐printed electroluminescent quantum dot (EL‐QD) devices. The mixed‐solvent approach effectively suppresses the coffee‐ring effect, enhances charge injection, and improves luminance, ultimately contributing to the optimization of EL‐

Enhanced Stability of Cd‐Free Quantum Dot Light‐Emitting Diodes via Yttrium Acetate‐Modified ZnMgO: Suppressing Mg Migration

open access: yesAdvanced Optical Materials, EarlyView.
A surface passivation strategy using yttrium acetate to suppress Mg ion migration from the ZnMgO electron transport layer is proposed. This treatment restores oxygen vacancies on the ZnMgO surface, enhancing device stability. The Cd‐free quantum dot light‐emitting diodes demonstrate a 65.5% increase in operational lifetime with an external quantum ...

Deep Blue Fluorescent OLEDs Based on a Solution and Solid‐State Emitter (SSSE): Investigations with 2‐Phenyl‐Naphthoxazole

open access: yesAdvanced Electronic Materials, EarlyView.
The blue fluorescent molecule 2‐phenyl‐naphth[2,3‐d]oxazole (Nzx) exhibits strong emission in both solution and solid states. Such behavior, referred to as solution and solid‐state emission (SSSE), makes Nzx a promising candidate for optoelectronic applications. This study highlights the potential of Nzx for the development of stable and efficient near

Al‐Doped LaTiO2N Prepared via Flame Spray Pyrolysis for Photocatalytic Hydrogen Evolution

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Flame spray pyrolysis enables the synthesis of La–Ti oxides with a simple perovskite‐type structure, and Al doping promotes the formation of the simple perovskite‐type La–Ti oxides. The Al‐doped LaTiO2N obtained by nitridation has a reduced defect concentration due to suppressed structural change, which contributes to the improvement of hydrogen ...

How Do I Look? The Impact of Unique and Intermediate Hues on Perceived Attractiveness

open access: yesColor Research &Application, EarlyView.
ABSTRACT Hering's unique hues (uHs) are hypothesized to exhibit enhanced perceptual salience due to their role in the opponent‐process theory of color vision, which posits that human color perception is structured around two opposing pairs: red–green and yellow–blue.

Acceptable Color Differences for Printed Color Samples

open access: yesColor Research &Application, EarlyView.
ABSTRACT Three experiments were carried out to investigate how different parameters affected the color difference evaluations. In each experiment, 450 pairs of printed samples, with the chromaticities surrounding nine CIE recommended color centers, were prepared, and the color difference of each pair was evaluated by a group of observers.
