Deterministic strain-induced arrays of quantum emitters in a two-dimensional semiconductor

Nature Communications, 2017
The emergence of quantum emitters in 2D materials has led to the quest for methods and designs enabling their controllable spatial positioning. Here, the authors use strain engineering to fabricate a deterministic array of quantum emitters in WSe2with ...

Strain tunable quantum emission from atomic defects in hexagonal boron nitride for telecom-bands

Scientific Reports, 2022
This study presents extending the tunability of 2D hBN Quantum emitters towards telecom (C-band − 1530 to 1560 nm) and UV-C (solar blind − 100 to 280 nm) optical bands using external strain inducements, for long- and short-range quantum communication ...

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

Advanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

From bound states to quantum spin models: chiral coherent dynamics in topological photonic rings

Nanophotonics
Topological photonic systems offer a robust platform for guiding light in the presence of disorder, but their interplay with quantum emitters remains a frontier for realizing strongly correlated quantum states.

Lead-related quantum emitters in diamond

Physical Review B, 2019
We report on quantum emission from Pb-related color centers in diamond following ion implantation and high temperature vacuum annealing. First-principles calculations predict a negatively-charged Pb-vacancy center in a split-vacancy configuration, with a zero-phonon transition around 2.3 eV.

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

Advanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Quasi-Degenerate Resonant Eigenstate Doublets of Two Quantum Emitters in a Closed Waveguide

Photonics
The physics of systems of quantum emitters in waveguide quantum electrodynamics is significantly influenced by the relation between their spatial separation and the wavelength of the emitted photons.

Quantum emitters in 2D materials [PDF]

Micro- and Nanotechnology Sensors, Systems, and Applications X, 2018
Recently discovered photon sources based on 2D materials are much more practical compared to their earlier counterparts due to high emission rate, robust performance in a range of environmental conditions and ease of photonic integration. It is expected that this platform will make a substantial contribution to a range of quantum optical applications ...

Decoupling Size and Electronic Effects in Doped SrTiO3 Photocatalysts Through Surface Area–Normalized CO2 Hydrogenation Rates

Advanced Functional Materials, EarlyView.
Exploring the photocatalytic reverse water–gas shift (RWGS) reaction on doped SrTiO3 nanoparticle films, reveals that normalizing catalytic rates by the catalyst's specific surface area (SSA) disentangled surface area effects from the catalyst's intrinsic material properties.

Suppression of local decay rate through energy quantum confinement effect in non-Markovian waveguide QED

PhotoniX
Waveguide quantum electrodynamics (QED) system manifests an ideal platform for studying many-body physics. When multiple emitters are coupled to a common waveguide, subradiant states may arise because of the waveguide-mediated interaction, leading to a ...
