Origin of Enhanced Efficiency and Reduced Roll‐Off in Organic Light‐Emitting Diodes Based on Pt(II) Complexes

Advanced Science, EarlyView.
Controlled Pt–Pt fine structure in square‐planar Pt(II) complexes governs metal–metal‐to‐ligand charge‐transfer (MMLCT) state formation, exciton dynamics, and organic light‐emitting diode performance. Short Pt–Pt contacts in Pt(fppz)2 enable coherent metal–metal coupling, sub‐microsecond emission and an external quantum efficiency of 29%, whereas ...

Monochromatic phototherapy in elderly patients: A new way of treating chronic pressure ulcers?

, 2003
Background and aims: Monochromatic pulsating light may have effects of importance for wound healing, and promising results were obtained in an open study on the healing of pressure ulcers, which motivated the present study. Methods: One hundred and sixty-

Far-Field Raman–Nath Diffraction of Polychromatic Light and a Ternary Data Transmission Scheme

Photonics
Raman–Nath diffraction is produced by a thin acoustic beam. The standing sound wave acts as a thin phase grating, causing monochromatic light to interact with it and diffract into multiple orders.

Visual acuity and contrast sensitivity under monochromatic yellow light [PDF]

This study investigates the impact of monochromatic lighting on visual acuity (VA) and contrast sensitivity (CS). Traditional assessments of VA and CS are typically conducted under the illumination of “white” light, but variations in color temperature ...

Design Rules for Quantitative Control of Intragrain Planar Defects in Halide Perovskites

Advanced Science, EarlyView.
Dose‐budgeted electron microscopy reveals the design rules governing intragrain planar defects in halide perovskites: {112}t ferroelastic twins proliferate with increasing tetragonality and grain size, whereas {111}c twins and stacking faults emerge as the lattice approaches cubic symmetry.

MOF‐Derived Cu‐TiO2/Alginate Micromotors for Buoyancy‐Regulated 3D Motion

Advanced Science, EarlyView.
In this work, cyanobacteria‐inspired sodium alginate (SA)/Cu‐TiO2/Fe3O4 hydrogel micromotors generate and encapsulate O2 microvesicles upon light irradiation, enabling buoyancy‐mediated Z‐axis upward migration and surface enrichment at the light‐exposed water‐air surface.

Integrated O2 and H2 Gas Therapy via Microneedle‐Assisted Photocatalytic Water Splitting for Accelerating Diabetic Full‐Thickness Skin Wound Healing

Advanced Science, EarlyView.
A concept of integrated O2 and H2 gas therapy is achieved using a gas‐producing material. PMP nanoparticles, fabricated from platinum, MIL‐101(Fe)‐NH2, and phosphotungstic acid, are integrated into bilayer gelatin methacryloyl microneedles for transdermal delivery. These microneedles enable integrated O2 and H2 gas therapy and promote wound healing via

The Stability of Oxide TFTs under Electrical Gate Bias and Monochromatic Light Illumination

, 2010
We have investigated a stability of oxide TFTs (IGZO) under electrical bias and monochromatic light illumination. Under -20 V gate bias, when 650 nm monochromatic illumination with intensity of 1 mW/cm2 was radiated, threshold voltage (Vth) was shifted ...

Twin‐Lever Multifunctional Meta‐Optics With High Longitudinal Tolerance

Advanced Science, EarlyView.
We introduce a single‐layer, CMOS‐compatible metasurface that allows for polarization‐programmable, achromatic broadband dual‐mode imaging with high longitudinal tolerance. The twin‐lever design combines bright‐field focusing and vortex‐based edge‐enhanced imaging while managing axial intensity distribution from 488 to 633 nm.
