Optical Diversity and Nanostructural Organization in the Colored Scales of Sternotomis

Advanced Optical Materials, EarlyView.
Vivid colors in Sternotomis beetles originate from nanoscale photonic architectures embedded within individual scales. Here, we provide a comparative optical and structural analysis of 57 scale types that reveal how ordered, quasi‐ordered, and disordered 3D networks tune color, saturation, and angular response.

Unraveling Mechanism of Photoluminescence in Hybrid Indium Halide Materials

Advanced Optical Materials, EarlyView.
Halide substitution in isolated [InHal6]3− octahedra reveals how bromide incorporation governs photoluminescence properties in hybrid indium halides. Ligand‐to‐metal charge transfer excitation followed by recombination produces a red‐shift and steadily increasing photoluminescence efficiency with increasing Br content.
