A flame‐spray‐pyrolysis method is presented to synthesize ultra‐bright CTS nanosheets with tunable NIR‐II emission. Achieving quantum yields up to 34%, these materials support high‐speed imaging and enable super‐resolution in vivo applications such as transcranial microcirculation mapping and macrophage tracking.

A novel three‐terminal PeLET device vertically integrated through a permeable electrode expands additional functionality beyond conventional two‐terminal devices. the specific mechanism is elucidated of E‐field penetration from the integrated capacitor unit to the LED via transient electroluminescence measurements. The PeLET device enables dual‐channel

Compact, robust, and ultralow‐loss on‐chip photonic devices are essential for densely integrated photonic chips. Here, the underlying radiation mechanism in topological valley edge states is unveiled and a new methodology of interface topology driven bandgap and wavevector engineering is proposed to thoroughly suppress their radiation losses, thereby ...

Programming Defects and Cavities into Colloidal Crystals Engineered With DNA
Seed‐mediated crystallization is adapted for colloidal crystals to design cavities and defect architectures through chemically programmed DNA sequences and appropriate seed particle geometry. This synthetic approach combines tenets from both atomic and colloidal crystallization to deliberately control defect formation in superlattices and enables the ...

Direct Laser Writing of Polymer Nanocomposites for Tunable Structural Color
Herein, direct laser writing is used to polymerize self‐assembled nanocomposite materials. Using fabrication parameters, the interparticle spacing is finely tuned beyond the thermodynamically stable state. This is exploited to generate wide gamut structural color in water.
