Delayed luminescence and thermoluminescence in laboratory-grown diamonds
Jiahui Zhao, Ben L. Green, Ben G. Breeze +4
The blue-green phosphorescence/thermoluminescence is most commonly observed in diamonds following excitation at or above the indirect band gap and has been explained by a substitut…
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…
Long Spin Coherence and Relaxation Times in Nanodiamonds Milled from Polycrystalline C Diamond
James E March, Benjamin D Wood, Colin J Stephen +8
The negatively charged nitrogen-vacancy centre (NV) in diamond has been utilized in a wide variety of sensing applications. The centre's long spin coherence and relaxation time…
Imaging damage in steel using a diamond magnetometer
L. Q. Zhou, R. L. Patel, A. C. Frangeskou +6
We demonstrate a simple, robust and contactless method for non-destructive testing of magnetic materials such as steel. This uses a fiber-coupled magnetic sensor based on nitrogen…
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…
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…
