From: Ground-State Depletion Nanoscopy of Nitrogen-Vacancy Centres in Nanodiamonds
a Fluorescence image of a super-resolved \({\text{NV}}^{ - }\) centre based on GSD nanoscopy. Dwell time 10 ms and 2 nm pixel size. b Transverse resolution as a function of depletion power. The discrepancy between experiment and theory is most likely due to imperfections in the host material and changes in the local environment of NDs compared to bulk diamond. The theory is based on NV centres in bulk diamond. c Image cross sections profile along the x-axis and y-axis with a FWHM resolution of 57 nm and 42 nm, respectively. The solid line represents the best fit
