Tunable Quasi‐Resonances in Polypyrrole Nanodisks

Advanced Optical Materials, EarlyView.
Polaronic carrier absorption enables electrochemically switchable quasi‐resonances in conducting polymer nanoantennas. ABSTRACT Redox‐tunable conducting polymers have emerged as promising materials for dynamic plasmonics and metasurfaces. However, only a few conducting polymers with particularly high conductivities (>1000 S/cm) have been reported to ...

Strong Photoluminescence Enhancement in All‐Dielectric Ge Thin Film Metasurfaces for Integration on the Si Platform

Advanced Optical Materials, EarlyView.
Germanium (Ge) all‐dielectric metasurfaces can be leveraged to strongly enhance the radiative emission from Ge layers grown on silicon‐on‐insulator substrates by industry‐standard processes. At room‐temperature, the narrowband photoluminescence (PL) intensity is enhanced by a factor ∼40× with respect to unstructured films.

Highly Crystalline CsPbBr3 Thin Films With Amplified Spontaneous Emission via High‐Pressure Recrystallization

Advanced Optical Materials, EarlyView.
High‐pressure recrystallization provides a reproducible route to high‐quality CsPbBr3${\rm CsPbBr}_{3}$ thin films. Optimized processing at 300 bar yields smooth, pinhole‐free, single‐phase 3D perovskite layers with tunable thickness, enhanced crystallinity, reduced amplified‐spontaneous‐emission threshold, improved photostability, and phase‐transition

Photodoping in Wide‐Bandgap Perovskite Solar Cells With MXenes

Advanced Optical Materials, EarlyView.
Ultrafast tandem spectroscopy and DFT modeling reveal the separate dynamics and the imbalance of electrons and holes in wide bandgap perovskite solar cells with MXene incorporation. The enhanced photoconversion performances of the devices are traced to photodoping, with selective hole trapping and suppressed recombination of electrons.
