1. A method of determining one or more characteristics of a photon emitter, the method comprising:

  • producing excitation illumination that is incident on a crystal film with one or more nitrogen vacancy centers, wherein the one or more nitrogen vacancy centers produces photoluminescence with an intensity in response to the excitation illumination;

    producing illumination from the photon emitter, the illumination being incident on the crystal film with the one or more nitrogen vacancy centers, wherein the illumination produced by the photon emitter quenches the intensity of the photoluminescence from the one or more nitrogen vacancy centers;

    detecting an amount of quenching of the intensity of the photoluminescence from the one or more nitrogen vacancy centers caused by the illumination of the photon emitter; and

    analyzing the amount of quenching of the intensity of the photoluminescence to determine the one or more characteristics of the photon emitter.
