Phosphorescence and donor-acceptor pair recombination in laboratory-grown diamonds
Jiahui Zhao, Ben L. Green, Ben G. Breeze +1
Intense "blue-green" phosphorescence is commonly observed in near colourless lab-grown high-pressure high-temperature (HPHT) diamonds following optical excitation at or above the i…
Sub-nanotesla magnetometry with a fibre-coupled diamond sensor
R. L. Patel, L. Q. Zhou, A. C. Frangeskou +12
Sensing small magnetic fields is relevant for many applications ranging from geology to medical diagnosis. We present a fiber-coupled diamond magnetometer with a sensitivity of (31…
Decoration of growth sector boundaries with single nitrogen vacancy centres in as-grown single crystal HPHT synthetic diamond
Philip L. Diggle, Ulrika F. S. D'Haenens-Johansson, Ben L. Green +5
Large (> 100 mm), relatively pure (type II) and low birefringence single crystal diamond can be produced by high pressure high temperature (HPHT) synthesis. In this study we ex…
Doubly-charged silicon vacancy center, photochromism, and Si-N complexes in co-doped diamond
B G Breeze, C J Meara, X X Wu +13
We report the first experimental observation of a doubly-charged defect in diamond, SiV2-, in silicon and nitrogen co-doped samples. We measure spectroscopic signatures we attribut…
Laser writing of individual atomic defects in a crystal with near-unity yield
Yu-Chen Chen, Benjamin Griffiths, Laiyi Weng +11
Atomic defects in wide band gap materials show great promise for development of a new generation of quantum information technologies, but have been hampered by the inability to pro…
Three-dimensional solid-state qubit arrays with long-lived spin coherence
C. J. Stephen, B. L. Green, Y. N. D. Lekhai +11
Three-dimensional arrays of silicon transistors increase the density of bits. Solid-state qubits are much larger so could benefit even more from using the third dimension given tha…
Electronic structure of the neutral silicon-vacancy center in diamond
B. L. Green, M. W. Doherty, E. Nako +5
The neutrally-charged silicon vacancy in diamond is a promising system for quantum technologies that combines high-efficiency, broadband optical spin polarization with long spin li…
The neutral silicon-vacancy center in diamond: spin polarization and lifetimes
B. L. Green, S. Mottishaw, B. G. Breeze +6
We demonstrate optical spin polarization of the neutrally-charged silicon-vacancy defect in diamond (), an defect which emits with a zero-phonon line at 946…

B. L. Green, B. G. Breeze, M. E. Newton
The defect in diamond formed by a vacancy surrounded by three nearest-neighbor nitrogen atoms and one carbon atom, , is found in of natural…
All-optical hyperpolarization of electron and nuclear spins in diamond
Ben L. Green, Ben G. Breeze, Gregory J. Rees +5
Low thermal polarization of nuclear spins is a primary sensitivity limitation for nuclear magnetic resonance. Here we demonstrate optically pumped (microwave-free) nuclear spin pol…
Laser writing of coherent colour centres in diamond
Yu-Chen Chen, Patrick S. Salter, Sebastian Knauer +11
Optically active point defects in crystals have gained widespread attention as photonic systems that can find use in quantum information technologies. However challenges remain in…
Electron paramagnetic resonance of the defect in -doped synthetic diamond
Ben L. Green, Matthew W. Dale, Mark E. Newton +1
Nitrogen is the dominant impurity in the majority of natural and synthetic diamonds, and the family of nitrogen vacancy-type () defects are crucial in our understa…
Production of oriented nitrogen-vacancy color centers in synthetic diamond
