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 ...

Single‐Photon Emitters in Thickness‐Controlled hBN Directly Grown on Silicon Platform

Advanced Optical Materials, EarlyView.
Direct, catalyst‐free CVD growth produces thickness‐controlled hBN films on SiO2/Si without transfer. Growth temperature, film thickness, and carbon incorporation tune the density and single‐photon fraction of defect emitters while preserving the hBN lattice structure.
