Enhanced Optical <sup>13</sup>C Hyperpolarization in Diamond Treated by High‐Temperature Rapid Thermal Annealing
Abstract Methods of optical dynamic nuclear polarization open the door to the replenishable hyperpolarization of nuclear spins, boosting their nuclear magnetic resonance/imaging signatures by orders of magnitude. Nanodiamond powder rich in negatively charged nitrogen vacancy defect centers has recently emerged as one such promising platform, wherein 13 C nuclei can …
