We demonstrate high resolution scanning fluorescence resonance energy transfer 10 microscopy between a single nitrogen-vacancy center as donor and graphene as acceptor. 11 Images with few nanometer resolution of single and multilayer graphene structures were 12 attained. An energy transfer efficiency of 30% at distances of 10nm between a single 13 defect and graphene was measured. Further the energy transfer distance dependence of 14 the nitrogen-vacancy center to graphene was measured to show the predicted d-4 15 dependence. Our studies pave the way towards a diamond defect center based versatile 16 single emitter scanning microscope.
