Abstract
Section titled âAbstractâ<p>Abstract:</p> <p>The singlet states of the negatively charged nitrogen-vacancy centers in diamond play a key role in its<br>optical spin control and readout. In this work, the hitherto unknown ionization energy of the singlet is<br>measured experimentally and found to be in the range 1.91–2.25 eV. This is obtained by analyzing photo-<br>luminescence measurements incorporating spin control and nitrogen-vacancy charge state differentiation,<br>along with simulations based on the nitrogen-vacancy’s master equation. This work establishes a proto-<br>col for a more accurate estimate of this ionization energy, which can possibly lead to improved readout<br>methods.</p>
