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

Advanced 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

Rigid Boron‐Fused Frameworks for Efficient Near‐Infrared Emission and Optical Gain Beyond 900 nm

Advanced Optical Materials, EarlyView.
Multiple‐resonance (MR)‐derived boron‐fused frameworks were integrated into narrow‐gap, long‐range charge‐transfer emitters to reduce structural relaxation and electron‐vibrational coupling. This strategy significantly decreases nonradiative losses, leading to improved near‐infrared (NIR) luminescence efficiency and low‐threshold amplified spontaneous ...
