Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing
An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...

Broadband Directional Thermal Radiation with Asymmetric Femtosecond Laser‐Processed Surfaces
Femtosecond laser processing is used to scalably create self‐organized angled microstructures which exhibit highly directional emissivity that occurs for all polarizations. Laser parameters are tuned to alter the surface features, control the direction of emission, and enhance the directional emissivity. Electromagnetic modeling is performed to analyze

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.

High‐Quality Free‐Standing Diamond Micromembranes for Nanoscale Quantum Sensing
We report a procedure for fabricating low‐damage free‐standing diamond micromembranes, and we show that this fabrication scheme preserves the optical and spin properties of state‐of‐the‐art shallow NV center quantum sensors, within nanometers of the diamond surface, while providing significant photonic enhancement.

Unraveling Mechanism of Photoluminescence in Hybrid Indium Halide Materials
Halide substitution in isolated [InHal6]3− octahedra reveals how bromide incorporation governs photoluminescence properties in hybrid indium halides. Ligand‐to‐metal charge transfer excitation followed by recombination produces a red‐shift and steadily increasing photoluminescence efficiency with increasing Br content.

Quantum Electrometry of Non‐Volatile Space Charges in Diamond
Charges are generated when nitrogen vacancy qubits in diamond are illuminated by light. Transport and trapping in an electric field leads to the formation of large, stable space charge patterns that dynamically screen applied electric fields, impacting electric field sensing and photoelectric detection.
