Direct Evidence of the Presence of Hybrid Charge Transfer State in a Perovskite Nanocrystal‐Polythiophene Blend Solid State Film

Advanced Materials Interfaces, EarlyView.
The photophysical properties of a hybrid solid state film, composed of a conjugated polymer and CsPbBr3 (zwitterionic sulfobetaine ‐capped) perovskite nanocrystals (NCs), are investigated by ultrafast spectroscopy and morphological characterization. The transient spectroscopy highlights the presence at the interface of a charge transfer state, and the ...

Mie‐Resonant Metasurfaces with Controlled Silicon Oxidation in Electron‐Beam Deposition

Advanced Materials Interfaces, EarlyView.
Electron‐beam deposition is optimized to prevent silicon oxidation by controlling chamber pressure and deposition rate, yielding refractive index values comparable to other methods. This tunability enables precise control of optical properties. Mie‐resonant metasurfaces exhibit strong, tunable collective resonances, allowing the fabrication of silicon ...

Plasmonic‐Strain Engineering of Quantum Emitters in Hexagonal Boron Nitride

Advanced Materials Interfaces, EarlyView.
Hexagonal boron nitride (hBN) defects attract interest for single‐photon emission in quantum technologies. This study presents an hBN‐gold nanocone platform to engineer emission centers. The findings reveal emission overlap with gold fluorescence, complicating attribution.
