Heteroleptic Ag(I) Complexes Bearing Benzothiazole and Benzoxazole Ligands for Orange‐Red Light‐Emitting Electrochemical Cells

open access: yesAdvanced Optical Materials, EarlyView.
Light‐emitting Electrochemical Cells (LECs) are appealing electroluminescent devices with potential application in low‐cost, large‐area display technology and disposable devices. In the manuscript, a novel family of bright photo‐ and electro‐active heteroleptic silver(I) is presented and comprehensively investigated.

Inverse‐Designed Superchiral Hot Spot in Dielectric Meta‐Cavity Toward Ultra‐Compact Enantioselective Detection

open access: yesAdvanced Optical Materials, EarlyView.
Linearly polarized incident light with normal incidence creates enhanced optical chirality hotspots on the metasurface. Several orders of magnitude optical chirality enhancement offers a promising route toward highly sensitive, compact chiral spectroscopy.

Donor‐Strength‐Driven Evolution From Charge‐Transfer to Polymethine Excited States in CurcBF2 Derivatives

open access: yesAdvanced Optical Materials, EarlyView.
Donor strength governs the excited‐state character and TADF behavior of donor‐acceptor‐donor borondifluoride curcuminoid derivatives. Increasing donor strength drives a transition from charge‐transfer TADF to a zwitterionic polymethine structure with predominantly local excited‐state emission and suppressed TADF.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced 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
