a Top and side view of the ITO structure. The dashed box marks the confocal scanning area. b Laser scanning confocal microscope image of the diamond with the ITO strip line. Emission of single NV centres can be observed over the whole area. The 20 μm wide ITO strip line is clearly visible as a region with increased background fluorescence
