Multi‐Dielectric Metasurfaces for Ultrabright, Tunable Structural Color and Reconfigurable Optical Filtering with Extraordinarily Large Color Span

Advanced Optical Materials, EarlyView.
Structural color generation is an emerging field for digital display and printing applications. This report presents a novel truncated‐cone design and the first use of GaP sandwiched between two layers of TiO2, demonstrating ultra‐bright, tunable colors with a record color gamut.

Exciton Radiative Lifetimes in Hexagonal Diamond Ge and SixGe1–x Alloys

Advanced Optical Materials, EarlyView.
Strong room‐temperature photoluminescence reported in hexagonal Ge conflicts with theory predicting a nearly dark band edge. First‐principles calculations of excitonic radiative lifetimes fill a key gap in this debate, showing that pristine hexagonal Ge remains intrinsically weakly emissive, while Si alloying only modestly shortens the lifetime and ...

Selective Reflection of Chiral Ferroelectric Nematic Liquid Crystals Tuned by Electric Field Along the Helix Axis

Advanced Optical Materials, EarlyView.
It is demonstrated that in chiral ferroelectric nematic liquid crystals sandwiched between electrically conducting transparent plates, the reflection color can be reversibly tuned by electric fields applied along the helix axis. The proposed theoretical model, assuming field‐induced coiling of the helix axis, accounts for all observations.
