A Simplified Hollow-Core Photonic Crystal Fiber SERS Probe with a Fully Filled Photoreduction Silver Nanoprism

open access: yesSensors, 2018
In this paper, a simplified hollow-core photonic crystal fiber surface-enhanced Raman scattering (SERS) probe is presented. Silver nanoprisms are grown with a photoreduction method and account for the SERS, which have better electromagnetic enhancement ...

Grayscale Photomasks Enable Noncontact Optical Patterning of Hydroxypropyl Cellulose Gels for Dynamic Art

open access: yesAdvanced Functional Materials, EarlyView.
Mask‐encoded UV exposure translates digital color information into pixel‐resolved structural‐color patterns in hydroxypropyl cellulose gels. Gaussian‐process‐guided calibration links UV processing conditions, wavelength, and mask opacity, enabling parallel fabrication of multicolor images in a single 10 s exposure.

Deformation‐Tolerant Functional Elastomer Overlayers for Haze‐Assisted Light Extraction and Color Conversion in Stretchable Mechanoluminescent Films

open access: yesAdvanced Functional Materials, EarlyView.
Functional elastomer overlayers are integrated onto stretchable ZnS:Cu‐PDMS mechanoluminescent films to regulate light after emission without modifying the emissive composite. NLC‐PU provides haze‐assisted light extraction to enhance green mechanoluminescence, while DCM‐NLC‐PU combines green‐to‐yellow‐orange color conversion with enhanced outward light
