Strong Plasmon–Exciton Coupling Tuned by Corner Etching of Gold Nanocubes and Nanotriangles

Advanced Optical Materials, EarlyView.
Systematic etching of gold nanocubes (AuNCs) and nanotriangles (AuNTs) reveals how nanoparticle morphology governs plasmon–exciton strong coupling. While rounding the corners of AuNCs weakens their coupling, triangular geometries robustly preserve deep strong coupling.

Metal‐Metal‐π Interaction: A Pathway to Construct Organic–Inorganic Excited‐State and Supramolecular Assembly

Advanced Optical Materials, EarlyView.
An organic–inorganic mixed excited state is designed and demonstrated by combining the metal–metal and π–π interactions within a supramolecular Pt2–pyrene assembly. Directional orbital overlap between the Pt and carbon atoms gives rise to a long‐lived triplet emission, strong emission polarization, exciton–exciton annihilation, and efficient exciton ...

Phototunable Polarization Volume Gratings Driven by Chiral Hydrazone Switches

Advanced Optical Materials, EarlyView.
Chiral hydrazone photoswitches incorporated into polarization volume gratings enable light‐driven, reversible modulation of optical properties. UV and blue light irradiation reversibly alter the hydrazone isomer ratio, leading to tunable diffraction efficiency and spectral response across the visible spectrum.

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

Advanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.
