摘要： A method of making measurements includes providing a sensor with at least one solid state electronic spin; irradiating the sensor with radiation from an electromagnetic radiation source that manipulates the solid state electronic spins to produce spin-dependent fluorescence, wherein the spin-dependent fluorescence decays as a function of relaxation time; providing a target material in the proximity of the sensor, wherein, thermally induced currents (Johnson noise) present in the target material alters the fluorescence decay of the solid state electronic spins as a function of relaxation time; and determining a difference in the solid state spins spin-dependent fluorescence decay in the presence and absence of the target material and correlating the difference with a property of the sensor and/or target material.
