The interaction between molecular electronic transitions and electromagnetic fields can be
enlarged to the point where distinct hybrid light–matter states, polaritons, emerge. The …

Colloidal quantum dots (QDs) are nanoscale semiconductor crystals with surface ligands
that enable their dispersion in solvents. Quantum confinement effects facilitate wave function …

We present an autonomous chemical synthesis robot for the exploration, discovery, and
optimization of nanostructures driven by real-time spectroscopic feedback, theory, and …

Quantum photonic technologies such as quantum communication, sensing or computation
require efficient, stable and pure single-photon sources. Epitaxial quantum dots (QDs) have …

Ultrathin dielectric gaps between metals can trap plasmonic optical modes with surprisingly
low loss and with volumes below 1 nm3. We review the origin and subtle properties of these …

Diamond photonics is an ever-growing field of research driven by the prospects of
harnessing diamond and its colour centres as suitable hardware for solid-state quantum …

Chemically made colloidal semiconductor quantum dots have long been proposed as
scalable and color-tunable single emitters in quantum optics, but they have typically suffered …

Single-photon emitters play an important role in many leading quantum technologies. There
is still no'ideal'on-demand single-photon emitter, but a plethora of promising material …

Moiré engineering is being intensively investigated as a method to tune the electronic,
magnetic and optical properties of twisted van der Waals materials. Advances in moiré …

Rare-earth-doped upconversion nanoparticles are attracting considerable attention because
of their stable, coherent, narrowband and multi-colour luminescence, which features less …
