Chiral Metasurfaces with Multidimensional Tunability for Optical Chiral States
Advanced Optical Materials, EarlyView.A novel bilayer perovskite chiral metasurface enables tunable transitions between BIC‐associated vortex centres and circularly polarized states via rotational symmetry control. Breaking rotational symmetry and applying in situ rotation to the upper layer allows precise, omnidirectional tuning of C points in momentum space. This evolution forms a Möbius‐

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.

High‐Speed, Continuous, Large‐Angle Nonmechanical Beam‐Steering with Liquid Crystal Etalons
Advanced Photonics Research, EarlyView.Liquid crystal (LC) is a strong candidate material for nonmechanical beam‐steering devices. This study proposes a new approach using three components: a superluminescent diode (SLD), an LC etalon, and a grating. Broad‐spectrum light from the SLD is passed through the LC etalon, generating wavelength‐swept light.

Advanced Photonics Research, EarlyView.Strong resonant amplification in polarization anisotropy in third harmonic generation (THG) response from isolated MoS2 disks with small structural ellipticity introduced during fabrication is reported. This is attributed to the high refractive index of the MoS2 disk that supports characteristic anapole resonances combined with the cubic dependence of ...

Local Structure–Luminescence Correlation in Eu3+‐Doped Phosphors: A Comprehensive Review
Advanced Photonics Research, EarlyView.This review discusses the correlation between local structure and the luminescent properties of Eu3+ ions, and also summarizes analytical methods for determining Eu3+ site occupancy. The luminescence properties of the phosphors are determined by the electronic configuration of the activator ions and are also affected by the coordinated environment of ...

Advanced Photonics Research, EarlyView.For multiresonance thermally activated delayed fluorescent emitters, the reverse intersystem crossing (RISC) process is of paramount importance. This review summarizes two approaches to enhance the RISC rate by improving spin‐orbit coupling: the heavy atom strategy and the long‐range charge‐transfer/short‐range charge‐transfer strategy.
