The Impact of Donor‐Orientation on the Emission Properties of Chlorinated Trityl Radicals

open access: yesAdvanced Optical Materials, EarlyView.
Chlorinated trityl radicals with electron‐donating groups enable efficient red emission for optoelectronics. Donor orientation and steric constraints regulate vibronic coupling, influencing luminescence. A novel trityl derivative with restricted donor alignment minimizes non‐radiative decay, enhancing quantum yield.

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

open access: yesAdvanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Polarization Management on Anisotropic Thin‐Film Lithium Niobate Platform

open access: yesAdvanced Photonics Research, EarlyView.
This review focuses on x‐cut thin‐film lithium niobate (TFLN), exploring strategies to mitigate anisotropy and mode hybridization. It covers polarization beam splitters, rotators, splitter‐rotators, polarizers, and polarization‐insensitive components. Key applications include polarization‐division multiplexing, polarization‐insensitive modulation, and ...

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

open access: yesAdvanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...
