Higher magnetic sensitivity through fluorescence manipulation by phonon spectrum control
First Claim
1. A method for determining an acoustic driving frequency for a diamond of a diamond nitrogen vacancy (DNV) sensor comprising:
- acoustically driving the diamond having nitrogen vacancies of the DNV sensor at a first frequency using an acoustic driver;
detecting, by a processing system, a first set of NV0 photon emissions and a first set of NV−
photon emissions from the DNV sensor;
acoustically driving the diamond of the DNV sensor at a second frequency using the acoustic driver;
detecting, by the processing system, a second set of NV0 photon emissions and a second set of NV−
photon emissions from the DNV sensor; and
selecting, by the processing system, the second frequency for acoustically driving the diamond with the acoustic driver to manipulate a phonon spectrum based on a wavelength difference between a peak of the second set of NV0 photon emissions and the second set of NV−
photon emissions from the DNV sensor.

Abstract
Methods and configuration are disclosed for providing higher magnetic sensitivity magnetometers through fluorescence manipulation by phonon spectrum control. A method for increasing the magnetic sensitivity for a DNV sensor may include providing a diamond having nitrogen vacancies of a DNV sensor and an acoustic driver and acoustically driving the diamond with the acoustic driver to manipulate a phonon spectrum of the DNV sensor. A DNV sensor may include a diamond having nitrogen vacancies, a photo detector configured to detect photon emissions from the diamond responsive to laser excitation of the diamond and an acoustic driver configured to manipulate a phonon spectrum for the DNV sensor by acoustically driving the diamond.
