Red Multi‐Resonant Thermally Activated Delayed Fluorescence Emitters as Bioimaging Agents

open access: yesAdvanced Optical Materials, EarlyView.
Multi‐resonant thermally activated delayed fluorescence (MR‐TADF) emitters have attracted strong interest for use in electroluminescent devices due to their high photoluminescence quantum yield and narrowband emission. These properties, along with red emission, are also crucial for bioimaging probes.

Optimized Growth and Manipulation of Light–Matter Interaction in Stabilized Halide Perovskite Nanowire Array

open access: yesAdvanced Optical Materials, EarlyView.
This study investigates CsPbBr3 nanowire (NW) array synthesis and stability using nanoporous anodized aluminum oxide (AAO) templates. Simulations identify optimal pore geometries for light–matter interactions (LMI). The ligand‐free modified inverse temperature crystallization (ITC) method is utilized for NW array growth, providing insights into a broad

Driving Micro‐Objects Using Optical Force due to Fluorescence Emission From Molecules

open access: yesAdvanced Optical Materials, EarlyView.
Emission of fluorescence from a micro‐object in a specific direction is expected to generate an optical force driving the object in the opposite direction of the emission, like a rocket. To demonstrate this ‘photon‐driven micro‐rocket’, we prepared dye‐doped polymer micro‐object (PMO) one surface of which was covered with metallic film; the PMO ...

Asymmetric Transmission and Diffraction Engineering in Ultrathin media via Coupled Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Grating‐insulator‐grating coupled crosstalking metasurfaces hosted on a silicon nitride membrane platform for asymmetric control of the diffraction pattern and asymmetric transmission. It is shown that exploiting the interferences of higher diffraction orders between the two metasurfaces and engineering the resulting modes enables AT in such ...
