C2LI: Enhancing Structural Color Sensing and Imaging via Complementary Color Laser Illumination

Advanced Optical Materials, EarlyView.
This article introduces complementary color laser illumination (C2LI) and demonstrates it to be an effective approach for engaging the visual system to enhance perceptual sensitivity and chromatic contrast. This enhances a human user's ability to detect subtle differences in sample or medium characteristics, enabling novel applications in colorimetric ...

A Type I Hyperbolic Metamaterial Driven by Phonons on ZnO

Advanced Optical Materials, EarlyView.
This article reports the first realization of a phonon‐driven type I hyperbolic metamaterial with ZnO/(Zn,Mg)O heterostructures. By adjusting the Mg content and layer thickness ratio, it establishes a clear framework for achieving and tuning the type I hyperbolic region via phonon resonances.

Bandgap Tuning of β‐(AlxGa1‐x)2O3 Nanosheets via Liquid Metal Interface Engineering

Advanced Optical Materials, EarlyView.
Ultrathin β‐(AlxGa1‐x)2O3 nanosheets with controlled composition are synthesized via low‐temperature squeeze‐printing of Al─Ga liquid alloys. Aluminium preferentially migrates to the surface of the liquid alloy, forming Al‐rich oxide layers with tunable bandgaps up to 6.4 eV. This compositionally precise approach enables the fabrication of 2D ultrawide‐

In Situ Transformation of Electrum Nanoclusters Embedded in Polymer Matrices Exhibit Near‐Infrared Emission With Quantum Yield Exceeding 70%

Advanced Optical Materials, EarlyView.
The AuAgNCs@OSTE nanocomposite, fabricated using off‐stoichiometric thiol‐ene polymerization, incorporates Au23‐xAgx(SAdm)15 nanoclusters and OSTE monomer. After UV curing, it reaches a maximum PLQY of 73% at 740 nm after 20 h of UV curing. After 72 h UV curing, PLQY reaches 60% at 850 nm, with minimal reabsorption losses due to the higher Stokes shift.
