Unraveling the Role of Surfactants in Micelle‐Templated Growth of Chiral Plasmonic Nanoparticles

Advanced Optical Materials, EarlyView.
Micelle template‐directed growth enables precise control over the chiroptical properties of gold nanorods. Comparison of surfactants with varying aliphatic tail lengths shows that longer tails increase groove inclination and reduce groove density. Optimized conditions for the longest‐tail surfactant (C18) yield slightly higher g‐factors than those ...

Directionally Asymmetric Holographic Imaging for Arbitrary Polarization States Using Janus Metasurfaces

Advanced Optical Materials, EarlyView.
We demonstrate single‐layer titanium dioxide Janus metasurface holograms that achieve directionally asymmetric imaging under forward and backward illumination. By integrating the Dammann grating principle with precise phase control, our design produces high‐fidelity holographic images for arbitrary polarization states at 532 nm, simplifying fabrication,

Strong and Weak Coupling Nanophysics with Free Electron Beams

Advanced Optical Materials, EarlyView.
This paper focuses on a short review of the study of the coupling between optical excitations at the nanometer scale, made possible by recent advances in free electron beam spectroscopies. In particular, plasmon–plasmon, plasmon–exciton, and plasmon–phonon couplings are reviewed. Abstract The work of Luis M.

Polar Indirect Valley as a Limiting Factor for Radiative Efficiency in Gold‐Based Mixed‐Valence Double Perovskites

Advanced Optical Materials, EarlyView.
This work addresses a common issue in many double perovskites: their weak luminescence. Using the example of promising infrared‐bandgap mixed‐valence gold halide double perovskites, it demonstrates strong polar electron‐phonon coupling. Temperature‐dependent spectroscopy reveals that bright polarons are favored at low temperature, while a dark low ...

Deep Seek to the Excited States: A Thermally‐Activated Jahn–Teller Effect Achieves Superior Sensitivity for Thermometry at Cryogenic Temperature

Advanced Optical Materials, EarlyView.
A Sb3+‐activated bismuth‐based halide single crystal shifts the onset temperature by ≈200 K. The confluence of the spin‐orbit interaction and the dynamic Jahn–Teller effect is responsible for maximizing the opposite emission changes at different temperatures. A high relative sensitivity (Sr) value of 18.9 % K−1 is obtained at 77 K.
