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…
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…
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…
Electron paramagnetic resonance and photochromism of in diamond
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…
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
A. M. Edmonds, U. F. S. D'Haenens-Johansson, M. E. Newton +5
The negatively charged nitrogen-vacancy (NV-) center in diamond is an attractive candidate for applications that range from magnetometry to quantum information processing. Here we…
Phonon Raman scattering of RCrO3 perovskites (R = Y, La, Pr, Sm, Gd, Dy, Ho, Yb, Lu)
M. Weber, J. Kreisel, P. A. Thomas +3
We report a systematic investigation of orthorhombic perovskite-type RCrO3 powder samples by Raman scattering for nine different rare earth R3+ cations (R = Y, La, Pr, Sm, Gd, Dy,…
Increasing the coherence time of single electron spins in diamond by high temperature annealing
Boris Naydenov, Friedemann Reinhard, Anke Lämmle +6
Negatively charged Nitrogen-Vacancy (NV) centers in diamond produced by ion implantation often show properties different from NVs created during the crystal growth. We observe…
Charge transfer effects, thermo- and photochromism in single crystal CVD synthetic diamond
R U A Khan, P M Martineau, B L Cann +2
We report on the effects of thermal treatment and ultraviolet irradiation on the point defect concentrations and optical absorption profiles of single crystal CVD synthetic diamond…
