Coupling of Er3+ ions and Plasmonic Modes in Vertical Nanocavities for Spectral Broadening in Telecom Bands

Advanced Materials Technologies, EarlyView.
Left: Illustration of the glass & nanostructures system and the NIR emission at 1.5 µm, where the colored spheres represent the Er3+ ions within the doped glass. Right: Representation of the Stark splitting of the 4I13/2 and 4I15/2 manifolds of the Er3+, illustrating how the plasmonic modes facilitate the emission from the broader Stark manifold ...

From Strain to Pressure: Atomically Resolved Mechanisms of Stress Dissipation in Emissive, Elastically Deformable Molecular Crystals Under Ambient and High Pressure

Advanced Optical Materials, EarlyView.
Molecular crystals must withstand both isotropic and anisotropic stress to function in flexible optoelectronics and high‐pressure devices. In situ high‐pressure single‐crystal X‐ray diffraction coupled with DFT‐D computations reveal how an emissive molecular crystal with interdigitated packing bends elastically at ambient‐pressure and remains ...

Multilevel Optical Programming of Intrinsic Vacancies in Solution‐Processed MoS2 Films for Retinomorphic Color Differentiation

Advanced Optical Materials, EarlyView.
Solution‐processed MoS2 films with intrinsic sulfur‐vacancy traps are used to integrate light sensing and memory in a simple two‐terminal pixel. Successive optical pulses program persistent, multilevel conductance states, while oxygen exposure enables rapid erasure.

Nanocrystal Quality–Controlled Scintillation in Porous YAG:Ce Aerogels

Advanced Optical Materials, EarlyView.
High‐temperature thermal treatment of YAG:Ce nanoscintillator aerogels increases light yield under ionizing radiation by up to eightfold without affecting timing performance. Additionally, low‐temperature atmospheric treatments reversibly modify the cerium oxidation state, revealing strong defect sensitivity and offering new strategies to optimize ...
