Quantum dots articles from across Nature Portfolio

An efficient way of realising a large number of telecom single-photon emitters for quantum communication is still missing. Here, the authors use a wide-field imaging technique for fast localization of single InAs/InP quantum dots, which are then integrated into circular Bragg grating cavities featuring high single-photon purity and indistinguishability.

This article presents a unique nanocomposite plasmonic-excitonic glass with extraordinary amplified optical properties: ultra-narrow photoluminescence (FWHM = 13 nm) and ultrashort photoluminescence lifetime (90 ps) at room temperature

Using an intrinsically stretchable nanocomposite of quantum dots, an elastomer and a hole transport polymer as an emissive layer, stretchable light-emitting diodes can be fabricated that exhibit high brightness even under 50% strain.

The researchers introduce an all-silicon optical PUF that enhances IoT device security through CMOS-compatible fabrication, showcasing five unique optical responses per pixel for advanced authentication and high information entropy.

This work explores the boundary between nanocrystal and relative bulk, expanding the photoresponse wavelength limitation of colloidal quantum dot photodetector up to very long wave infrared.

Modulating amyloid protein phase separation and fibrilization may help in addressing neurodegenerative diseases. This study demonstrates that halogen-doped graphene quantum dots can modulate these processes in TDP-43 in both nucleus and cytoplasm.

An article in Angewandte Chemie International Edition resurfaces metal halide perovskite nanocrystals with a reactive, liquid ligand to produce efficient and stable red perovskite light-emitting diodes.

An article in Nature Materials shows that a ‘quantum dot molecule’ — two fused and electronically coupled quantum dots — can easily switch between two distinct emission colours when induced by an electric field.

An article in the Journal of the American Chemical Society decorates type-I CdS-ZnS core–shell quantum dots with metallic domains to activate them as hydrogen evolution photocatalysts.
