Advanced Optical Materials, EarlyView.The compositional engineering of Sn‐halide perovskite with alkylammonium chloride, combined with graded heterojunction formation using fullerene, is shown to significantly enhance crystallinity and reduce trap densities. Consequently, the resulting photodetectors achieve a 63.4% external quantum efficiency and a specific detectivity of 1.38 × 1011 ...

Directional Lasing from a 3D Blue Phase Photonic Crystal
Advanced Optical Materials, EarlyView.This work presents the first directional lasing from millimeter‐scale monocrystalline 3D photonic crystals, specifically Blue Phases (BPs), overcoming prior limitations of random lasing in polycrystals. These 3D soft photonic crystals enable highly directional, circularly polarized, mirrorless lasing via resonant polarization modes, offering the ...

Linker‐Free Covalent DNA Functionalization of Quantum‐Grade Nanodiamonds
Advanced Optical Materials, EarlyView.Nanodiamond (ND) surface is terminated with azide groups via nucleophilic substitution and decarboxylative azidation. The resulting azidated NDs display high click reactivity while retaining the spin and charge properties of nitrogen‐vacancy centers.

Cloaking and Antennas: From Theoretical Paradigms to Next‐Generation Intelligent Systems
Advanced Optical Materials, EarlyView.The inception of electromagnetic cloaking sparked an immediate question: Can antennas be made invisible? Two decades later, this review charts the intertwined progress of major cloaking strategies (from transformation optics to scattering cancellation), metasurface technology, and their application to antennas, revealing how AI‐enabled devices are ...

Hierarchical Twist: Chirality Across Scales in Cellulose Cholesterics
Advanced Optical Materials, EarlyView.Hierarchical left‐ and right‐handed chiral nematic structures are observed in a solvent‐free thermotropic cellulose derivative. Free‐standing films show hierarchical twisted structures whose pitches respond differently to uniaxial strain: left‐handed pitches increase, ones decrease.
