Dynamic Structural Colors in Cholesteric Cellulose Composites: Achieving Spatial and Temporal Control

open access: yesAdvanced Optical Materials, EarlyView.
By combining static and time‐resolved optical, structural, and rheological techniques, we demonstrate that the blue‐shift upon solidification of ethyl cellulose‐acrylic acid mesophases corresponds to the reorientation of cholesteric domains. Modulating the mesophase chain mobility and photopolymerization reaction kinetics enables solid chiral nematic ...

Toward Enhancing Chiro‐Optical and Magneto‐Optical Properties of Magnetic Nanocrystals by Surface Plasmons

open access: yesAdvanced Optical Materials, EarlyView.
Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

Halogen Bonding‐Enabled Stabilization of Copper(I) Cluster Scintillators in Aqueous Environments

open access: yesAdvanced Optical Materials, EarlyView.
A new class of halogen bonding‐strengthened copper(I) cluster‐based X‐ray scintillators is developed, with higher lattice symmetry, reduced trap density, and enhanced stability in polar chemical environments surpassing the performance of halogen‐free counterparts and other conventional scintillators. Abstract Scintillators are essential in applications,

Optimization of ZnGa2O4:Cr3+ Nanoparticles Synthesis Exhibiting Persistent Luminescence for Nanoplastic Labelling and Imaging in Daphnia Magna

open access: yesAdvanced Optical Materials, EarlyView.
ZnGa2O4:Cr3+ nanoparticles with persistent luminescence are synthesized and optimized for labeling microplastics via cryomilling. The solvothermal method provides superior optical properties, enabling background‐free imaging. These luminescent particles are successfully used to trace microplastic uptake and distribution in Daphnia magna, offering a ...
