All‐Optical Electric Field Sensing with Nanodiamond‐Doped Polymer Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
The photoluminescence (PL) of fluorescent nanodiamonds (FNDs) in a polymer‐based capacitor device is sensitive to electric fields. When an external electric field is applied, the PL intensity of the negatively charged nitrogen‐vacancy center (NV‐) increases, while that of the neutrally charged NV center (NV0) decreases.

On‐Surface Indigo‐Based Bimolecular Coordination Networks with Programmable Regular or Vitreous Structure

open access: yesAdvanced Functional Materials, EarlyView.
A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...

Integrated Metallo‐Dielectric 3D Hotspots From High Refractive Index Nanodiamond‐Plasmonic Gold Cryosoret Nano‐Assemblies for Photonic Crystal Enhanced Fluorescence

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a novel sensing platform using metallo‐dielectric cryosoret nano‐assemblies and lossless photonic crystals to overcome limitations of conventional plasmonic biosensors. The hybrid system enhances both electric and magnetic field interactions, enabling amplified fluorescence, ultralow detection limits, and prism‐free, objective‐free ...

Photoresponsive Gas‐Permeable Membranes: Fundamentals, Innovations, and Prospects

open access: yesAdvanced Functional Materials, EarlyView.
Photoresponsive gas‐permeable membranes can be potentially used for smart packing, carbon capture, hydrogen purification, and optical gas valves due to their remote and non‐contact activation, precise spatial and temporal control, and reversible switching capabilities.

Narrow Inhomogeneous Distribution and Charge State Stabilization of Lead‐Vacancy Centers in Diamond

open access: yesAdvanced Functional Materials, EarlyView.
Lead‐vacancy (PbV) centers in diamond are expected to be a building block of quantum network nodes owing to a large ground state splitting, which suppresses phonon interaction. In this study, multiple PbV centers with nearly identical photon frequencies and stable charge state are fabricated by high‐pressure and high‐temperature anneal up to 2300 °C ...
