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.
