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.

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 ...

A ferroelectric‐gated phototransistor (FGPT) enables linear and multilevel modulation of photoconductance through partial polarization switching and photogating effects. The device achieves photonic non‐volatility over a 153 dB dynamic range and performs in‐sensor processing under unstructured illumination, demonstrating enhanced face recognition ...

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 ...
