Optimized Growth and Manipulation of Light–Matter Interaction in Stabilized Halide Perovskite Nanowire Array

open access: yesAdvanced Optical Materials, EarlyView.
This study investigates CsPbBr3 nanowire (NW) array synthesis and stability using nanoporous anodized aluminum oxide (AAO) templates. Simulations identify optimal pore geometries for light–matter interactions (LMI). The ligand‐free modified inverse temperature crystallization (ITC) method is utilized for NW array growth, providing insights into a broad

Chiral Sensing of Amino Acids under Visible Light via Hydroxypropyl Cellulose Gels

open access: yesAdvanced Optical Materials, EarlyView.
Hydroxypropyl cellulose gels enable visible‐light‐based chiral detection of amino acid enantiomers. This study showcases their structural color properties for distinguishing phenylalanine and alanine enantiomers. The gels exhibit pH‐responsive color changes, high sensitivity at low concentrations (0.2 wt.%), and long‐term stability, offering ...

Rapid Electro‐Thermal Micro‐Actuation of Flat Optics Enabled by Laser‐Induced Graphene on Colorless Polyimide Substrates

open access: yesAdvanced Optical Materials, EarlyView.
Laser‐induced graphene (LIG) on a colorless polyimide (CPI) substrate functions as both an electrical heater and a heat spreader, enabling rapid electro‐thermo‐optic actuation. The system achieves reflective beam scanning up to 2 kHz and diffractive beam steering with 0.5‐millidegree resolution and a 0.9 s response time, showcasing LIG‐CPI as a soft ...
