In this work, we prepare six near-surface NV ensembles, determine their depths by 19F NMR, and determine their NMR sensitivities using a home-built fluorescence microscope with a 40 μm excitation diameter. We use one of our most sensitive NV ensembles for detection of 11B NQR in hBN exfoliated onto the diamond surface. To prepare our near surface NV ensembles, we implant nitrogen at energies from 1.5 to 7 keV. We experimentally demonstrate that minimizing sample sensor stand-off minimizes measurement time to achieve SNR = 3, t(SNR=3). We then exfoliated 100nm thick flakes of hBN on a diamond and measured the NQR signal intensity of 11B with CPMGXY8-N, to demonstrate the sensitivity of these samples. We estimate these NV ensembles should have shorter t(SNR=3) than a single NV for 11B in hBN for excitation diameters as small as 8 μm.
