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

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
Advanced Photonics Research, Volume 6, Issue 5, May 2025.Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
