Fig. 4

a Planar view of 2D PL mapping (4 × 4 μm2) probed at the depth of 31 μm of the SHI irradiated area showing isolated individual 1D NV− chains as isolated individual bright luminescence spots; b Visualization of 3D luminescence patterns of individual 1D NV− chains reconstructed by discrete 2D PL scan probed at different depth from 0 to 30 μm; c Color center PL spectra evolution along the SHI trajectory from the sample surface to a depth of 30 μm; d A comparison of integrated PL intensity as a function of depth probed on (red) and off (black) a single SHI ion track.
