FRET‐Enhanced Singlet Fission in Pentacene Derivatives

open access: yesAdvanced Optical Materials, EarlyView.
Excitation of molecules in blend funnels light energy via Förster resonance energy transfer toward reaction centers where singlet fission generates multiple excitons. Abstract Conversion of solar energy with high quantum efficiencies is a key challenge in energy technologies. Excitation energy transfer (EET) mechanisms, such as Förster resonance energy

Hundreds of Nanocoulomb Electron Acceleration Driven by Multipetawatt Laser in Subcritical Density Plasmas

open access: yesAdvanced Photonics Research, EarlyView.
Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Tunable Multifunctional Terahertz Coding Metasurface for Polarization Manipulation

open access: yesAdvanced Photonics Research, EarlyView.
Coding metasurfaces (CMs) offer versatile control over electromagnetic waves. Herein, a tunable multifunctional terahertz (THz) metasurface integrated with vanadium dioxide (VO2) is presented, enabling propagation‐phase manipulation of linearly polarized waves and hybrid‐phase control of circularly polarized waves.
