Optical and Electronic Spin Properties of Fluorescent Micro- and Nanodiamonds upon Prolonged Ultrahigh-temperature Annealing, led by Nicholas Nunn, was published in JVST,
High-temperature annealing is a promising but still mainly unexplored method for enhancing spin properties of nitrogen-vacancy (NV) centers in diamond particles. In this paper we investigate the effects of conventional annealing (900 °C) against annealing at a much higher temperature of 1600 ºC for particles ranging in size from 100 nm to 15 µm. The results provide guidance for future studies and optimization of high temperature annealing of fluorescent diamond particles for applications relying on the spin properties of NV centers in the host crystals.
