Radiative Cooling by Green(er) Solvents‐Upcycled Polyvinyl Chloride From Drug Blisters Waste

Advanced Optical Materials, EarlyView.
This study explores upcycling poly(vinyl chloride) (PVC) from used pharmaceutical blisters into sustainable radiative cooling materials. Using solvent separation and membrane fabrication, PVC was converted into white membranes paired with aluminum foil.

Broadband Directional Thermal Radiation with Asymmetric Femtosecond Laser‐Processed Surfaces

Advanced Optical Materials, EarlyView.
Femtosecond laser processing is used to scalably create self‐organized angled microstructures which exhibit highly directional emissivity that occurs for all polarizations. Laser parameters are tuned to alter the surface features, control the direction of emission, and enhance the directional emissivity. Electromagnetic modeling is performed to analyze

High‐Quality Free‐Standing Diamond Micromembranes for Nanoscale Quantum Sensing

Advanced Optical Materials, EarlyView.
We report a procedure for fabricating low‐damage free‐standing diamond micromembranes, and we show that this fabrication scheme preserves the optical and spin properties of state‐of‐the‐art shallow NV center quantum sensors, within nanometers of the diamond surface, while providing significant photonic enhancement.

Unraveling Mechanism of Photoluminescence in Hybrid Indium Halide Materials

Advanced Optical Materials, EarlyView.
Halide substitution in isolated [InHal6]3− octahedra reveals how bromide incorporation governs photoluminescence properties in hybrid indium halides. Ligand‐to‐metal charge transfer excitation followed by recombination produces a red‐shift and steadily increasing photoluminescence efficiency with increasing Br content.

Harnessing Ultrafast Optical Pulses for 3D Microfabrication by Selective Tweezing and Immobilization of Colloidal Particles in an Integrated System

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...
