Photochemical afterglow of single organic molecules with wide‐range tunable lifetime

PhotoMat, EarlyView., 2023
“All‐in‐one” strategy was used to achieve photochemical afterglow in single organic molecule, with second‐to‐hour range tunable lifetime by tailoring the electron‐withdrawing ability of substituents. Abstract Background Photochemical afterglow that relies on slow release of photons from the chemical energy stored by light pre‐irradiation has emerged as

Metasurfaces and Metadevices for Topological Electromagnetic Waves

Advanced Physics Research, EarlyView.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary
