Abstract
Section titled “Abstract”Nitrogen vacancy (NV <sup xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>-</sup> ) centers possess exceptional sensitivity to magnetic field even under ambient condition. The optically detectable electron spins and the atomic size make it a promising candidate for advanced magnetic resonance imaging (MRI) technique with nanoscale spatial resolution. In this work, diamond particles with NV <sup xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>-</sup> centers were deposited by microwave plasma chemical vapor deposition (MPCVD) under gaseous N <sub xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>2</sub> dopant and were fixed on the fabricated scanning probe as a magnetic sensor. While the existence of NV <sup xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>-</sup> center was determined by Raman spectroscopy, the photoluminescence intensity at 2.87 GHz microwave frequency was decreased by an optically detected magnetic resonance (ODMR) system. It implies that the NV <sup xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>-</sup> spin state can be manipulated and read out using optical excitation.
