Abstract
A method of introducing NV centers in single crystal CVD diamond material is described. One step of the method comprises irradiating diamond material that contains single substitutional nitrogen to introduce isolated vacancies into the diamond material in a concentration of at least 0.05 ppm and at most 1 ppm. Another step of the method comprises annealing the irradiated diamond to form NV centers from at least some of the single substitutional nitrogen defects and the introduced isolated vacancies.
